Answer:

77460 g

Explanation:

To solve this problem first we convert molecules into moles, using Avogadro's number:

3.47x10²⁶ molecules ÷ 6.023x10²³ molecules/mol = 576.12 moles

Then we convert 576.12 CuCl₂ moles into grams, using its molar mass:

576.12 mol * 134.45 g/mol = 77460 g

So the answer is 77460 g, or 77.46 kg.

Answer:

x^2 - a^2

Explanation:

Explanation:

B. filter and remove liquid and solid waste

Answer:

Calculate he number of moles you have by taking the Mass / molar mass. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4.

Cell theory states that cell living organisms are composed of at least one cell, which are the basic unit of life. Cells are always produced from other living cells, and cannot spontaneously generate

The sum of all coefficients = 7

Given

The word equation

Required

The sum of all coefficients

Solution

The chemical equation can be expressed in terms of:

Convert the word equation into a chemical equation(skeleton) :

Ga + Cl₂ → GaCl₃

Balanced equation

2Ga + 3Cl₂ → 2GaCl₃

The sum of all coefficients :

= 2+3+2

= 7

Answer:

20.1797 grams.

Explanation:

The molecular formula for Neon is Ne. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Neon, or 20.1797 grams.

The dog would not  be in the part of first trophic level of an energy pyramid.

Energy pyramid is defined as a model that show the flow of energy from one tropic or feeding level to next tropic or feeding level in an ecosystem.

There are basically three energy pyramid.

Trophic level is defined as the source based on their nutrition or food, organisms occupy a specific place in a food chain.

First trophic level contains only green plants and producers. Their plants and product where consumed by second level of organisms.

Thus, the dog would not  be in the part of first trophic level of an energy pyramid.

Answer:

1.5moles of S;

Explanation:

The reaction expression is given as:

            S +  O₂   →   SO₂

Number of moles of SO₂  = 1.5moles

From the balanced reaction expression:

              1 mole of SO₂ will be produced from 1 mole of S;

  So;      1.5moles of SO₂  will produce 1.5moles of S;

The moles of S₂ needed to produce 1.50 moles of SO₂ gas is 1.5 mol.

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

The reaction is

S +  O₂   →   SO₂

The number of moles of SO₂ is 1.50 mol

1 mole of S produce 1 mole of SO₂

Then, 1.5 mole of S will produce 1.5 SO₂

Thus, the moles are 1.5.

Answer:

No

Explanation:

There are no interactive forces (i.e., attraction or repulsion) between the particles of a gas.

The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy.

Answer:

D. The cup reflects yellow light but absorbs all other colors of light.

Explanation:

The cup in the shop appears yellow because the cup reflects yellow light but absorbs all colors of light.

Due to the materials the cup is made of, it is able to specifically reflect yellow and absorb other radiation types.

The color we see are products of the part of visible radiations they reflect.

The cup in this instance reflects yellow and absorbs other color.

Answer:

Go to your periodic table and look for each element. Find the mass for Aluminum, Nitrogen, Oxygen, and Hydrogen.

After you find those, for each compound you must add them together and find the least amount of sig figs after the decimal point.

For the first compound, Al(NO3)3, you will have a total of

1 Aluminum atom

3 Nitrogen atoms

9 Oxygen atoms

Aluminum has 26.982 g/mol

Nitrogen has 14.007 g/mol

Oxygen has 15.999 g/mol

Now multiply those numbers by the amount of atoms of each element.

(1)26.982 g/mol = 26.982 g/mol

(3)14.007 g/mol = 42.021 g/mol

(9)15.999 g/mol = 143.991 g/mol

now add all of those numbers together, and you see that their least significant figure after the decimal is 3, so round to 3 digits after the decimal point.

26.983 + 42.021 + 143.991 = 212.994

now do the same for the other compound

to start you off.. you have

6 Hydrogen atoms

3 Oxygen atoms

Hydrogen has 1.009 g/mol

Oxygen has 15.999 g/mol

the least significant figure after the decimal point is 3, so round you 3 digits after the decimal point.

after you finish getting your totals, you. until them and find the greatest sig fig over all. comment on this if you need further instruction :)
