Answer:
Output voltage = 600 V
Explanation:
Using the transformer equation which simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.
Number of input turns/Number of output turns = Voltage of input/voltage of output
10/50 = 120V/voltage of output
Voltage of output = 120 V/0.2
Voltage of output = 600 V

Calculate the molar mass of the following compounds in g/mol.
CH3CO2H
Answer:
60g/mol
Explanation:
By using nucleon numbers given on the periodic table, the mass of 1 mole of each element is:
C= 12g
H= 1g
O= 16g
Since molar mass is the sum of the masses of each element present in the compound,
Molar Mass (Mr) = 12+3(1)+12+16(2)+1 = 60g/mol

What is the percent by mass in a solution with 10.0 grams of solute and 25.0 grams of solvent?
Answer:
Percent by mass of solute is (10/35) x 100 = 28.57%
Percent by mass of solvent is (25/35) x 100 = 71.43%
Explanation:
10.0 grams of solute
25.0 grams of solvent
Total Mass = 35 grams
percent by mass = (Mass A / Total Mass) x 100
Percent by mass of solute is (10/35) x 100 = 28.57%
Percent by mass of solvent is (25/35) x 100 = 71.43%
A transformer has ten turns of wire on the input side and 50 turns of wire on the output side. If the input voltage is 120 V, what will the output voltage be?
Answer:
600 V
Explanation:
The transformer equation helps us to calculate the relationship between the ratio of the number of turns of coils in the input and output sources to their respective voltages.
It states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.
Number of input turns/Number of output turns = input voltage/output voltage
10/50 = 120V/output voltage
output voltage = 120 V/0.2
Output voltage = 600 V

Which functional group defines a ketone?
−NH
−PO4
−Na
=O
The functional group that defines a ketone is =O and the correct option is option 4.
What are Ketones?
Ketones are a common functional group in organic chemistry. Ketones have important physiological properties. As a result, they are a part of several sugars and compounds involved in medicinal use such as cortisone, an anti-inflammatory.
In ketones, the carbonyl group has 2 hydrocarbon groups attached to it. These can be either the ones containing benzene rings or alkyl groups. Ketone does not have a hydrogen atom attached to the carbonyl group.
Therefore, the functional group that defines a ketone is =O and the correct option is option 4.

Answer:
In CO, the oxidation number of carbon is +2 and that of oxygen is -2
In H2 the oxidation number of hydrogen is zero
In CH3OH, the oxidation state of carbon is -2, that of hydrogen is +1 and that of oxygen is -2
Explanation:
The oxidation number of an element in any compound is defined as the electrical charge that the element appears to have as determined by a set of arbitrary rules. These rules make it possible to calculate the oxidation number of an atom in a compound given the oxidation numbers of other atoms in the same compound.
In CO, the oxidation number of carbon is +2 and that of oxygen is -2
In H2 the oxidation number of hydrogen is zero
In CH3OH, the oxidation state of carbon is -2, that of hydrogen is +1 and that of oxygen is -2
A5.3 * 1012 kg satellite is 1.800 m from another satellite that has a mass of 3.5 x 108 kg. What is the gravitational
force between the satellites?
3.82 x 10N
6.87 x 107N
5.72 % 1014 N
1.03 * 1018 N
Answer:
The gravitational force between the satellites is [tex]3.81\times 10^{10}\ N[/tex].
Explanation:
Mass of satellite 1, [tex]m_1=5.3\times 10^{12}\ kg[/tex]
Mass of satellite 2, [tex]m_2=3.5\times 10^8\ kg[/tex]
Distance between masses is 1.8 m
It is required to find the gravitational force between the satellites. The formula used to find the force between two masses is given by :
[tex]F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{5.3\times 10^{12}\times 3.5\times 10^8}{(1.8)^2}\\\\F=3.81\times 10^{10}\ N[/tex]
So, the gravitational force between the satellites is [tex]3.81\times 10^{10}\ N[/tex].

A student is trying to dissolve 20 grams of sugar in a beaker containing 250 milliliters of water at room temperature. What can the student do to make the sugar dissolve faster in the water?
Answer:
They can warm up the water. Sugar dissolves much faster in warm/hot water.
A perfect example of this is when you put sugar in your hot coffee/tea -> it will dissolve almost immediately. If you put sugar in cold water, you will have to stir it for quite some time before it dissolves.
How do the HOX genes in the paddlefish match the HOX genes in human
Answer:
Hox are transcription factors that are evolutionarily conserved across bilaterians and, therefore, they share sequence homology between paddlefish and humans .
Explanation:
The Hox genes represent a family of homeodomain transcription factors that play roles in the development of the axial and appendicular skeleton, being therefore critical during embryonic development. In this case, the human Hox genes are homologous to homeobox genes found in the paddlefish. These genes have a DNA-binding domain of 60 amino acids which is evolutionarily conserved in bilaterian species including paddlefish and human species.

Explanation:
Ok so water is H2O and cabon dioxide in the air is CO2, so the water goes through the carbon dioxide and makes acid rain H2SO4.
Now we have our limestone which is CaCO3.
What happens is that the acid breaks apart our limestone into Ca2+ and CO3 2-. This then reforms into Calcium bicarbonate Ca(CO3)2.
Calcium bicarbonate is soluble in water and is hence washed away by the rain eroding the limestone.

When potassium chromate (K2CrO4) is added to a solution containing 0.500 g silver nitrate (AgNO3), solid silver chromate (Ag2CrO4) is formed. a) Determine the theoretical yield.
Answer:
Theoretical Yield = 0.4882 grams
Explanation:
Potassium Chromate = K2CrO4 Molar mass: 194.1896 g/mol
Silver Nitrate = AgNO3 Molar mass: 169.87 g/mol
Silver(I) Chromate = Ag2CrO4 Molar mass: 331.73 g/mol
Potassium Nitrate = KNO3 Molar mass: 101.1032 g/mol
K2CrO4 + 2AgNO3 = Ag2CrO4 + 2KNO3
Potassium Chromate + Silver Nitrate = Silver(I) Chromate + Potassium Nitrate
Ratio 1:2 = 1:2
0.5g AgNO3
AgNO3 Molar mass: 169.87 g/mol
2AgNO3 = 339.74grams
0.5/339.74 = 0.0014717
Ag2CrO4 Molar mass: 331.73 g/mol
0.4882 grams
Theoretical Yield = 0.4882 grams

Answer:
The answer to your question is given below
Explanation:
1. Data obtained from the question include:
Hydrogen ion concentration, [H+] = 1x10^-9M
pH =..?
pH = - log [H+]
pH = - log 1x10^-9
pH = 9
2. Data obtained from the question include:
pOH = 3
pH =.?
Recall:
pH + pOH = 14
pH + 3 = 14
Collect like terms
pH = 14 - 3
pH = 11
3. Data obtained from the question include:
Hydroxide ion concentration, [OH-] = 1x10^-2M
pH =..?
First, we shall determine the pOH. This is illustrated below
pOH = - Log [OH-]
pOH = - Log 1x10^-2
pOH = 2
Finally, we can obtain the pH as follow:
pH + pOH = 14
pOH = 2
pH + 2 = 14
Collect like terms
pH = 14 - 2
pH = 12
4. Data obtained from the question include:
pOH = 7
pH =.?
Recall:
pH + pOH = 14
pH + 7 = 14
Collect like terms
pH = 14 - 7
pH = 7
