Density is defined as the ratio of mass to the volume.

The mathematical expression is given as:

$d =\frac{m}{v}$

where, d = density

m = mass and v= volume

Plug in the value of density i.e. $2.70 g/cm^{3}$ and volume i.e. $275 cm^{3}$ in above formula;

$2.70 g/cm^{3} =\frac{m}{275 cm^{3}}$

$2.70 g/cm^{3}\times 275 cm^{3} = m$

$m = 742.5 g$

Now from conversion factors, 1 kg = 1000 g

Thus, mass of aluminium in kg = $\frac{742.5}{1000}$

= $0.7425 kg$

Hence, mass of aluminium in kg = $0.7425 kg$

In Part A, you found the amount of product (1.80 mol P2O5 ) formed from the given amount of phosphorus and excess oxygen. In Par

Finger [1]

First step is to balance the reaction equation. Hence we get P4 + 5 O2 => 2 P2O5

Second, we calculate the amounts we start with

P4: 112 g = 112 g/ 124 g/mol – 0.903 mol

O2: 112 g = 112 g / 32 g/mol = 3.5 mol

Lastly, we calculate the amount of P2O5 produced.

2.5 mol of O2 will react with 0.7 mol of P2O5 to produce 1.4 mol of P2O5.

This is 1.4 * (31*2 + 16*5) = 198.8 g

Answer: The rate of disappearance of $NO_2$ is $3.5\times 10^{-5}M/s$

Explanation:

The given chemical reaction is:

$2NO_2\rightarrow 2NO+O_2$

The rate of the reaction for disappearance of $NO_2$ is given as:

$\text{Rate of disappearance of }NO_2=-\frac{\Delta [NO_2]}{\Delta t}$

Or,

$\text{Rate of disappearance of }NO_2=-\frac{C_2-C_1}{t_2-t_1}$

where,

$C_2$ = final concentration of $NO_2$ = 0.00650 M

$C_1$ = initial concentration of $NO_2$ = 0.0100 M

$t_2$ = final time = 100 minutes

$t_1$ = initial time = 0 minutes

Putting values in above equation, we get:

$\text{Rate of disappearance of }NO_2=-\frac{0.00650-0.0100}{100-0}\\\\\text{Rate of disappearance of }NO_2=3.5\times 10^{-5}M/s$

Hence, the rate of disappearance of $NO_2$ is $3.5\times 10^{-5}M/s$

What is the specific heat (J/g°C) of a metal object whose temperature increases by 3.0°C when 17.5 g of metal was heated with 38

Verizon [17]

Answer:

a. 0.73

Explanation:

Given data

Added heat (Q): 38.5 J

Change in the temperature (ΔT): 3.0°C

Mass of the metal (m): 17.5 g

Specific heat of the metal (c): ?

We can determine the specific heat of the metal using the following expression.

Q = c × m × ΔT

c = Q / m × ΔT

c = 38.5 J / 17.5 g × 3.0°C

c = 0.73 J/g.°C

If the pOH of vinegar is 9.45, what is its [OH− ]?

7nadin3 [17]

Answer:
[OH⁻] = 3.54 × 10⁻¹⁰ M

Solution:

pOH is related to [OH⁻] as,

pOH = - log [OH⁻]

Putting value of pOH,

9.45 = -log [OH⁻]

Solving for [OH⁻],

[OH⁻] = 10⁻⁹·⁴⁵ ∴ 10 = Antilog

[OH⁻] = 3.54 × 10⁻¹⁰ M
