Which statement best describes what makes a base weak? A base is weak when it forms few ions in water. A base is weak when only a little of it is dissolved in water. A base is weak when its concentration is high. A base is weak when it totally forms ions in water.

The nitrogen gas and the oxygen gas will both occupy 50 liters.

Let us recall form the kinetic theory of gases that a gas is in constant random motion. The gas does not have a specific volume but takes on the volume of the container since it will expand and fill the container.

The volume occupied by the two gases will be the same as the volume of the container. Hence, the nitrogen gas and the oxygen gas will both occupy 50 liters.

Answer:

100 L

Explanation:

Use Boyle's Law, p1v1 = p2v2.

p1 = 4 atm

v1 = 50L

p2 = 2 atm

v2 = ?

p1v1 = p2v2

(4 atm) (50L) = (2 atm) (v2)

v2 = (4 atm)(50L) / (2 atm) = 100 L

Explanation:

In the core of the sun, hydrogen is produced by nuclear fusion. when the sun ages, it starts to run out of the hydrogen. when it runs out, nuclear fusion can't generate heat, and then the sun expands, becoming a red giant.

Explanation:

Step 1: Calculate the moles of HNO₃ in the initial solution

A student has 475 mL (0.475 L) of a 4.5 M HNO₃ (4.5 mol HNO₃/ L) solution.

0.475 L × 4.5 mol HNO₃/ L = 2.1 mol HNO₃

He leaves the top of the container open, so water will evaporate, but the moles of HNO₃ will remain the same.

Step 2: Calculate the final concentration of the solution

2.1 moles of HNO₃ are in 347 mL (0.347 L) of solution.

[HNO₃] = 2.1 mol / 0.347 L = 6.1 M

Answer:

They made this graphics, how they measured the gas and how this affected the climate change horribly.

They created these images to show how the gas was measured and how the climate change was adversely affected the greenhouse gases.

A greenhouse gas is a gas that produces the greenhouse effect by both absorbing and emitting radiant energy at thermal infrared wavelengths. The five main greenhouse gases in the atmosphere of Earth are ozone, carbon dioxide, methane, and water vapor.

The gases that trap heat in the earth's atmosphere are referred to as greenhouse gases. The earth's surface warms during the day when the light beams through the atmosphere.

The earth's surface cools at night, redistributing heat into the atmosphere. However, part of the heat is captured by the atmosphere's greenhouse gases.

Therefore, how the climate change was adversely impacted the greenhouse gases must ask the team.

Explanation:

amount of baking soda = 2.01 g

---> 2.01 g NaHCO3 × (1 mol NaHCO3/84.007 g NaHCO3)

= 0.024 mol NaHCO3

mass of the product = 1.28 g

Possible reactions:

NaHCO3(s) ---> NaOH(s) + CO2(g)

0.024 mol NaHCO3 × (1 mol NaOH/1 mol NaHCO3)

= 0.024 mol NaOH × (39.997 g NaOH/1.mol NaOH)

= 0.96 g NaOH

2NaHCO3(s) ---> Na2O(s) + 2CO2(g) + H2O(g)

0.024 mol NaHCO3 × (1 mol Na2O/2 mol NaHCO3)

= 0.012 mol Na2O × (61.9789 g Na2O)

= 0.73 g Na2O

2NaHCO3(s) ---> Na2CO3(s) + CO2(g) + H2O(g)

0.024 mol NaHCO3 × (1 mol Na2CO3/2 mol NaHCO3)

= 0.012 mol Na2CO3 × (105.9888 g Na2CO3/1 mol Na2CO3)

= 1.27 g Na2CO3

Conclusion:

Based on the mass of the product in the crucible and comparing it with the predicted product mass in different reactions, I conclude that Na2CO3 is the most likely product in the crucible.

Answer:

P2 = 4.76 atm

Explanation:

Given:

T1 = 235K. P1 = 3.80 atm

T2 = 298K. P2 = ?

Here, we use Gay-Lussac's law:

P1/T1 = P2/T2

Solving for P2, we get

P2 = (T2/T1)P1

= (298K/238K)(3.80 atm)

= 4.76 atm

Answer:

2C₄H₁₀(g) + 13O₂(g) —> 8CO₂(g) + 10H₂O(g)

Explanation:

The balanced equation for the reaction between butane and oxygen to produce carbon dioxide and water can be written as follow:

C₄H₁₀ + O₂ —> CO₂ + H₂O

Next, we shall balanced the equation. This is illustrated below:

C₄H₁₀ + O₂ —> CO₂ + H₂O

There are 4 atoms of C on the left side and 1 atom on the right side. It can be balance by writing 4 before CO₂ as shown below:

C₄H₁₀ + O₂ —> 4CO₂ + H₂O

There are 10 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 5 before H₂O as shown below:

C₄H₁₀ + O₂ —> 4CO₂ + 5H₂O

There are 2 atoms of O on the left side and a total of 13 atoms on the right side. It can be balance by writing 13/2 before O₂ as shown below:

C₄H₁₀ + 13/2O₂ —> 4CO₂ + 5H₂O

Multiply through by 2 to express in whole number ratio.

2C₄H₁₀(g) + 13O₂(g) —> 8CO₂(g) + 10H₂O(g)

Thus, the equation is balanced.

Answer:

Explanation:

This is an example of a limiting reactant question, and is very common as a general chemistry problem.

We first see the balanced equation, that is:

We first need to find the limiting reactant

We see that 0.56 g of copper(II) chloride (CuCl2) reacts with 0.64 g of potassium iodide (KI) . So, let's convert those amounts into moles.

Copper(II) chloride has a molar mass of

134.45 g/mol . So in 0.56 g of copper(II) chloride, then there exist

0.56g134.45g/mol≈4.17⋅10−3 mol

Potassium iodide has a molar mass of

166 g/mol . So, in 0.64 g of potassium iodide, there exist
