Answer:

We know that we'll get one mole CO2 for every 1 mole CH4. So let's calculate how many moles are in 50 g of CH4 by dividing it's mass by it's molar mass (16 g/mole). I get 3.125 moles. The equation says we should get the same number of moles of CO2, so set moles CO2 = 3.125 moles. Then we can find the mass of CO2 by multipying by the molar mass of CO2 (44 g/mole). We should expect 138 grams of CO2.

Answer:

Given the balanced equation

CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)

we know that we'll get one mole CO2 for every 1 mole CH4. So let's calculate how many moles are in 50 g of CH4 by dividing it's mass by it's molar mass (16 g/mole). I get 3.125 moles. The equation says we should get the same number of moles of CO2, so set moles CO2 = 3.125 moles. Then we can find the mass of CO2 by multipying by the molar mass of CO2 (44 g/mole). We should expect 138 grams of CO2.

What would you use to determine whether an acid or alkali has been added to a solution?

KIM [24]

Answer:

B. Indicator

Explanation:

An indicator is used to determine whether an acid or alkali has been added to a solution.

Indicators can be liquid or a paper called litmus paper. There also some digital forms of indicators that can tell whether an acid or alkali has been added to a solution.

An acid and alkali will change the pH of a solution.
pH is the amount of hydrogen ions that are in a solution
So, these changes in the pH when an acid or alkali is introduced is usually monitored using indicators.
Examples of indicators are litmus paper, methyl orange, methyl red, bromothymoblue

What would form a solution?

Ipatiy [6.2K]

Answer:

B. Mixing a solute and a solvent

Explanation:

Hello,

In this case, solutions are defined as liquid homogeneous mixtures formed when two substances having affinity are mixed. It is important to notice that the two substances are known as solute, which is added to other substance that is the solvent. Therefore, answer is B. Mixing a solute and a solvent.

Notice that when two insoluble substances are mixed no solution is formed. Furthermore, if two solutes together or a solute and a precipitate are mixed, no liquid homogeneous solution is formed, as commonly solutes are solid, nevertheless, when liquid, one should have to act as the solvent.

Best regards.

How many moles of gallium chlorate, Ga(ClO3)3, must react in order to produce 674 kJ of energy according to the following reacti

Valentin [98]

Answer:

10.3 mol Ga(ClO₃)₃

Explanation:

Let's consider the following balanced thermochemical equation.

2 Ga(ClO₃)₃(s) ⇒ 2 GaCl₃(s) + 9 O₂(s) ΔH = - 130.4 kJ

According to the balanced thermochemical equation, 130.4 kJ of heat are released when 2 moles of gallium chlorate react. The number of moles of gallium chlorate that must react to produce 674 kJ of energy is:

674 kJ × 2 mol Ga(ClO₃)₃/130.4 kJ = 10.3 mol Ga(ClO₃)₃

Neither n2 nor o2 are greenhouse gases because

Katyanochek1 [597]

Neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.

<h3>What are greenhouses gases?</h3>

Greenhouse gases trap heat in the atmosphere causing the temperature of the planet to rise.

Greenhouse gases cause the greenhouse effect.

<h3>What is the greenhouse effect?</h3>

The greenhouse effect is the warming up of the planet due to greenhouse gases.

Greenhouse gases include

carbondioxide
methane
nitrous oxide and
water vapour

So, neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.
