Answer:
0.2491
Explanation:
1mole of a gas contains 6.02 × 10²³molecules
x moles will contain 3.408 × 10²¹
x = 1 × 3.408 × 10²¹/ 6.02 × 10²³
= 5.66 × 10^-3moles
Mole = mass/ molar mass
mass = Mole × molar mass
= 5.66 × 10^-3 × 44.01
= 249.0966 × 10^-3
= 0.2490966
to 4 decimal places = 0.2491

An ammonia solution has a pH of 8.25. What is its [OH-]?
pH + pOH = 14
If pH=8.25, then:
pOH = 14 - 8.25 = 5.75
pOH = -log[OH-]
5.75 = -log[OH-]
-5.75 = log[OH-]
10^(-5.75) = [OH-]
[OH-] = 0,0000017783
[OH-] = 1,78×10^(-6) mol/dm³

A plant uses the energy from sunlight to create oxygen and glucose from carbon dioxide and water which statement is true about the changes that have occurred
Answer:
The correct answer choice is A. A chemical change has occurred because new compounds have been produced.
Explanation:
A physical change is defined as a change in which there is alteration in shape, size etc. No new substance gets formed in these reactions.Example: Melting of ice A chemical change is defined as a change in which a change in chemical composition takes place. A new substance is formed in these reactions.Example: photosynthesis
Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.
Thus the true statement is a chemical change has occurred because new compounds have been produced.
A chemical reaction produces formaldehyde, with a chemical formula of CH2O. Carbon is in Group 4A, oxygen is in Group 6A, and hydrogen is in Group 1A on the periodic table. In one to two sentences, describe the bonds in a molecule of formaldehyde in terms of valence electrons.(2 points)
This problem is providing a comparison on the atoms forming formaldehyde, CH₂O, in terms of the groups they are in, C in group 4A, O in group 6A and H in group 1A, and it is asking for a description about the bonds once they are bonded in a formal Lewis dot structure.
In such a way, the attached file shows the Lewis dot structure, in which we can find two bonds between the two hydrogen atoms and the carbon one, and also, a double bond between carbon and oxygen.
The aforementioned is explained by bearing to mind the concept of octet, which states that elements in groups 4A, 5A, 6A and 7A are able to complete 8 valence electrons after bonding.
Thus, since carbon is in group 4A we infer it needs 4 more electrons to complete the octet, and that is achieved due to the 4 bonds it is having with the two hydrogen atoms and double bond with the oxygen atom.
In addition, since oxygen is in group 6A, we infer it needs two more electrons to complete its octet, which is attained via the double bond it has with the carbon atom. For hydrogen, however, it can complete one bond at maximum, because it is in group 1A, which means it can complete two valence electrons after bonding.

Answer:-Angiosperms
Explanation:-Angiosperms are plants that bloom and bear fruit. The word angiosperm is derived from two Greek words, Angeion and Sperma . Angeion means "vessel" and sperma means "seed".
A flexible vessel contains 78.00 L of gas at a pressure of 1.50 atm. Under conditions of constant temperature
and moles of gas, what is the pressure of the gas when the volume of the vessel is tripled?
The pressure of the gas when the volume of the vessel is tripled is 0.50 atm.
To find the volume of the gas, we use Boyle's law which states that for a given mass of gas at constant temperature, the pressure is inveresly proportional to its volume. This is stated mathematically as P ∝ 1/V.
So, PV = constant
P₁V₁ = P₂V₂ where P₁ = initial pressure of gas = 1.50 atm, P₂ = final pressure of gas, V₁ = initial volume of gas = 78.00 L and V₂ = final volume of gas = 3V₁ (since the volume of the gas is tripled)
So, making P₂ the subject of the formula, we have
P₂ = P₁V₁/V₂
Substituting the values of the variables into the equation, we have
P₂ = P₁V₁/V₂
P₂ = 1.50 atm × V₁/3V₁
P₂ = 1.50 atm/3
P₂ = 0.50 atm
So, the pressure of the gas when the volume of the vessel is tripled is 0.50 atm.

a fisherman in a boat is drinking a of hot coffee. the large lake below his boat is full of cold water. which statement is an accurate comparison of the lake water and the coffee?
Answer:
see below
Explanation:
The lake will have more total thermal energy but the particles in the coffee will be moving faster.
A comparison of hot coffee and cold lake is, the heat from the coffee will be absorbed by the cold lake through convection method of heat transfer.
Conservation of energy
The principle of conservation of energy states that the total energy of an isolated system is always conserved.
Heat lost by the hot coffee = Heat absorbed by the cold lake
Heat transfer processHeat from the coffee will be absorbed by the cold lake through convection method of heat transfer.
Thus, a comparison of hot coffee and cold lake is, the heat from the coffee will be absorbed by the cold lake through convection method of heat transfer.
