Converting temperature of 68°F to °C gives 20 °C.
Converting temperature of 68°F to K gives 293 K.
<h3>What is temperature conversion?</h3>
Temperature conversion is the process of converting the measurement units of the temperature recorded in a particular unit to another unit.
The various units of Temperature include;
- degree Celsius
- degree Fahrenheit
- degree Kelvin
Temperature is measured with thermometer and it records the hotness or coldness of a body.
<h3>Converting 68°F to °C</h3>
F = 1.8C + 32
(F - 32/1.8) = C
(68 - 32) / 1.8 = C
20 ⁰C = 68 ⁰F
<h3>Converting 20°C to K</h3>
0 °C = 273 K
20 °C = 273 + 20 = 293 K

Answer:
A
Explanation:
I think the answer would be A
Answer:
The total number of atoms is 12 + 22 + 11 = 45, so carbon atoms are 12/45 of the total.
Explanation:
X(OH)₂ + 2HCl = XCl₂ + 2H₂O
n{X(OH)₂}=m{X(OH)₂}/M{X(OH)₂}
n(HCl)=c(HCl)v(HCl)
n{X(OH)₂}=n(HCl)/2
m{X(OH)₂}/M{X(OH)₂}=c(HCl)v(HCl)/2
M{X(OH)₂}=2m{X(OH)₂}/{c(HCl)v(HCl)}
M{X(OH)₂}=2*8.65/{2.50*56.9*10⁻³}=121.6 g/mol
M(OH)=17.0 g/mol
M(X)=121.6-17.0*2=87.6 g/mol ⇒ X=Sr, strontium
Sr(OH)₂ + 2HCl = SrCl₂ + 2H₂O
