Answers are:

3.07 × 10^4 = 30,700.

3.07 × 10^-4 = 0.000307.

3.07 × 10^-6 = 0.00000307.

3.07 × 10^6 = 3,070,000.

1) 10^4 = 10 × 10 × 10 × 10.

10^4 = 10,000.

3.07 × 10^4 = 3.07 × 10,000.

3.07 × 10^4 = 30,700.

2) 10^-4 = 1 ÷ (10 × 10 × 10 × 10).

10^-4 = 1 ÷ 10,000.

10^-4 = 0.0001.

3.07 × 10^-4 = 3.07 × 0.0001.

3.07 × 10^-4 = 0.000307.

3) 10^-6 = 1 ÷ (10 × 10 × 10 × 10 × 10 × 10).

10^-6 = 1 ÷ 1,000,000.

10^-6 = 0.000001.

3.07 × 10^-6 = 3.07 × 0.000001.

3.07 × 10^-6 = 0.00000307.

4) 10^6 = 10 × 10 × 10 × 10 × 10 × 10.

10^6 = 1,000,000.

3.07 × 10^6 = 3.07 × 1,000,000.

3.07 × 10^6 = 3,070,000.

A rectangular fence is 3 times as long as it is wide. The perimeter is 60ft. Find the dimensions of the fence
Mashutka [201]

Answer:

The length of the fence is 22.5ft and the width of the fence is 7.5ft.

Explanation:

To solve this problem we will turn this question into an equation.

The equation for the perimeter of a rectangle is 2l + 2w = perimeter.

In the question we were given the perimeter so we can go ahead and plug this in.

2l + 2w = 60

In the question we are also told that the fence is 3 times as long as it is wide. This means that 1l = 3w. We can now subsitute l for 3w so that we only have one variable.

2(3w) + 2w = 60

Now we can simply use algebra to solve for w.

6w + 2w = 60

8w = 60

w = 7.5

Now that we know the value of w we can find the value of l since we know 1l = 3w.

l = 3w

l = 3(7.5)

l = 22.5

The length of the fence is 22.5ft and the width of the fence is 7.5ft.

Determine the number of grams of C4H10 that are required to completely react to produce 8.70 mol of CO2 according to the followi
Nitella [24]

Answer:

126.4 g of C_{4}H_{10} are required

Explanation:

Balanced reaction: 2C_{4}H_{10}+13O_{2}\rightarrow 8CO_{2}+10H_{2}O

According to balanced reaction-

8 moles of CO_{2} are produced from 2 moles of C_{4}H_{10}

So, 8.70 moles of CO_{2} are produced from (\frac{2}{8}\times 8.70) moles of C_{4}H_{10} or 2.175 moles of C_{4}H_{10}

Molar mass of C_{4}H_{10} = 58.12 g/mol

So, mass of C_{4}H_{10} required = (2.175\times 58.12)g = 126.4 g

Hence 126.4 g of C_{4}H_{10} are required

Which statement is true about the relationship between entropy and spontaneity? O Spontaneous reactions tend to lead to higher e
dimulka [17.4K]

Answer:

The true statement is: Spontaneous reactions tend to lead to higher entropy.

Explanation:

The spontaneity of a reaction is linked to the value of Gibbs free energy (ΔG°). The more negative is this value, the more spontaneous is a reaction. At the same time, Gibbs free energy depends on enthalpy (ΔH°) and entropy (ΔS°), according to the following expression:

ΔG° = ΔH° - T.ΔS°

We can see that higher entropies (higher ΔS°) lead to more negative ΔG°, thus, more spontaneous reactions.
