Chemistry
1 answer:
kotegsom [21]3 years ago
6 0

Answer:

There are 19 atom sin total in antimony silicate, Sb_4(SiO_4)_3.

Explanation:

Number of antimony atoms = 4 × 1 = 4

Number of silicon atoms = 3 × 1 = 3

Number of oxygen atoms = 3 × 4 = 12

Number of atoms in antimony silicate:

= 4 + 3 + 12 = 19

There are 19 atom sin total in antimony silicate, Sb_4(SiO_4)_3.

Consider 5.00 L of a gas at 365 mmHg and 20. ∘C . If the container is compressed to 2.50 L and the temperature is increased to 3
pickupchik [31]

First convert celcius to Kelvin.

20 + 273 = 293K

31 + 273 = 304K

Now we can set up an equation based on the information we have.

V1 = 5

P1 = 365

T1 = 293

V2 = 5

P1 = x

T2 = 304

The equation be:  \frac{(5)(365)}{293} = \frac{5x}{304}

Now just solve.

1825/293 = 5x/304

Cross multiply.

554800 = 1465x

Divide both sides by 1465

x = 378.7030717 which can then be rounded to 378.7 mmHg

what is the percent by mass of NaHCO3 in a solution containing 20.0 g of NaHCO3 dissolved in 600.0 ml of water
Ne4ueva [31]
%(NaHCO3)= ((mass NaHCO3)/(mass NaHCO3 + mass water))*100%

m=Volume*Density
Density of water =1 g/ml
m(water) = Volume(water)*Density(water) = 600.0 ml * 1g/ml=600g water

%(NaHCO3)= ((20.0 g)/(20.0 g + 600 g))*100%=0.0323*100%=32.3%
