Something on a man i think it’s crocs
Normal blood ph ranges from 7.35 to 7.45 which is basic
For the first question, i think the correct answer is the third option. When a gas is formed, it is <span>the most conclusive in determining whether a chemical reaction has taken place given that none of your reactants is a gas.
For the second question, the statement is true.
For the third question, the correct answer is the last option.</span>
Answer:
936g/mol
Explanation:
To find the molar mass of a molecule, you find the sum of the molar masses of each atom in the molecule.
This compound has 40 carbon atoms, 60 Hydrogen atoms, 10 Nitrogen atoms, 12 Oxygen atoms, and 2 Sulphur atoms.
The molar mass of:
- Carbon is 12g/mol
- Hydrogen is 1g/mol
- Nitrogen is 14g/mol
- Oxygen is 16g/mol
- Sulphur is 32g/mol
![(12 \times 40) + (60 \times 1) + (14 \times 10) + (16 \times 12) + (32 \times 2) = 936](https://tex.z-dn.net/?f=%2812%20%5Ctimes%2040%29%20%2B%20%2860%20%5Ctimes%201%29%20%2B%20%2814%20%5Ctimes%2010%29%20%2B%20%2816%20%5Ctimes%2012%29%20%2B%20%2832%20%5Ctimes%202%29%20%3D%20936)
The answer of temperature change is mentioned below
<h3>
What is Temperature Change ?</h3>
The change in temperature is given by
ΔT=Final Temperature −Initial Temperature
Measurements of temperature
It is a measure of the degree of hotness or coldness of a body
To determine temperature changes,
the initial and final temperature of the iron and water is recorded.
For Iron
Iron at higher temperature is dipped in water
Water is at lower temperature so there will be change in temperature fo both
These data are recorded
Temperature change = Final temperature - Initial temperature.
a) Temperature change for metal = 200 - 100 = 100 0C
Temperature change for water = 22.5
Temperature change for both = 23.3
b) For water 0.7
For iron Metal 76.6
