Answer:
2 moles of solute.
Explanation:
Molarity is defined as number of moles of solute present in one litre of solution.
Hence one molar solution of NaCl means 1 mole of NaCl is present in 1 litre of solution.
Molarity = 
For 1 litre of solution 1 mole of solute is required to make a one molar solution.
Hence for 2 litres of solution we require 2 moles of solute to keep it one molar.
Answer:
1 Spinal fluid
2 Milk
3 Saliva
4 Urine
5 Gastric content
Explanation:
Hello there!
In this case, according to the given information, it turns out firstly necessary for us to calculate the pH of both gastric content and spinal fluid by using the following equations and works:

Thus, we rank them as follows:
1 Spinal fluid
2 Milk
3 Saliva
4 Urine
5 Gastric content
Regards!
Answer:1 and 5
Explanation:
The zeros in 500 aren’t in the middle of 2 non number nor does it have a decimal in the number
Answer:
(C) CH_2
Explanation:
An electrophile is an atom that loves electron. For an atom to be able to pull electrons closer to itself, it must be electron deficient and with a partial positive charge.
From the structure give, N is a highly electronegative atom and it is a nucleophile. This implies it loves the nucleus which is positively charged.
The Carbon atom attached to it is an electrophile because it has a lower electronegativity thereby leaving a partial positive charge on it. Therefore, the carbon will be attracted to the nucleophile.
PV = n RT
P: pressure =10atm
V volume
n number of mole = 35.8 moles
R universal gas constant = 0.082
T: The temperature= 70°C= 343.15 Kelvin
V= (n RT) / P = 35.8 x 0.082 x 343.15 / 10 = 100.7 ≈ 101 L
V = 101L
