what is the equivalent weight of sodium trioxocarbonate (IV) in the reaction between Hydrochloric acid and sodium trioxocarbonate (IV)?
Correct answer gets brainliest. This is urgent.
Answer:
Standard acid-base reaction in two stages:
Na2CO3 + HCl → NaHCO3 +NaCl
NaHCO3 + HCl → NaCl + CO2 + H2O
If only a small quantity of acid is added (and the overall solution remains above pH 7), the reaction would stop at stage 1 and you’d be left with an aqueous solution of sodium chloride and sodium bicarbonate. Adding more acid would lead to the bicarbonate being converted to carbon dioxide and water, with the CO2 coming out of solution as a gas and more sodium chloride being produced.

1)Where are irons in our body ?
2) Is there some difference in the way metals and non– metals react with acid ?
Answer:
iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin. Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues.
2( non- metals generally do not react with acids but metals react with acids and produce hydrogen gas that burns with a 'pop' sound. You must have noticed that copper does not react with dilute hydrochloric acid even on heating but it reacts with sulphuric
Describe a dinner you would like to eat that includes all the main nutrients, but is low in the nutrients that you should limit.
Dinner including grilled chicken,roasted brussels sprouts and cooked quinoa have all main nutrients and are low in carbohydrates.
What are carbohydrates?
A carbohydrate is defined as a bio-molecule which consists of carbon,hydrogen and oxygen atoms which are usually in the ratio of 2:1 with the empirical formula C[tex]_n[/tex](H₂O)[tex]_n[/tex].
This term is most commonly used in biochemistry as a synonym of saccharide which is a group of sugars, starch and cellulose.
They perform various functions in living organisms. They serve as an energy source and as well as structural components . They are a key component in providing nutrition and are found in wide variety of natural as well as processed foods.

8. A sample of 16.0g of a metal oxide, MO, is reduced to 12.8g of the metal, M.
What is the relative atomic mass, Ar, of M?
A 32 B 64 C 80 D 128
Answer:
B 64
Explanation:
i think b 64 is right answer.......
The relative atomic mass is 64g and the metal is copper(Cu).
What is relative atomic mass?The weighted average of the masses of an element’s isotopes in comparison to the mass of a carbon-12 atom is known as relative atomic mass (Ar).The ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant is defined as relative atomic mass (Ar) or atomic weight.The mole ratio for M and O in the compound MO is 1:1.
The mass of oxygen in the 16g compound is 16.0 - 12.8 = 3.2g.
The relative atomic mass of O is 16g. The number of moles of O in the 3.2g is 3.2/16 = 0.2.
Since the M and O gave the same number of moles in the MO, that is their mole ratio is 1:1, then the number of moles of the M in the MO is also 0.2.
Therefore, if 0.2 mole if M weighs 12.8g, then 1 mole of M will weigh 1 x 12.8/0.2 = 64g/mole.
The mole of an element is its relative atomic mass.
Therefore, the relative atomic mass of M is 64g.
Hence, option B is the correct answer.

How many moles of NH3 are produced when 0.60 mol of nitrogen reacts with hydrogen in N2 + 3H2 ----> 2NH3
Answer:
0.80 mol
Explanation:
n(H)/n(N) = 1/3
n(N) = 3×0.60
n(N) = 1.8 mol
n(N) in excess = 1.80-0.60 = 1.20 mol
n(N)/n(NH3) = 3/2
n(NH3) = 2/3×1.20 = 0.80 mol

2 CH3Oh + 3O2 + 2CO2 + 4 H2O how many liters of carbon dioxide will be formed form 6 moles of oxygen
Answer:
89.6 L of CO₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2CH₃OH + 3O₂ —> 2CO₂ + 4H₂O
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles CO₂.
Next, we shall determine the number of mole CO₂ produced by the reaction of 6 moles of O₂. This can be obtained as follow:
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles CO₂.
Therefore, 6 moles of O₂ will react to produce = (6 × 2)/3 = 4 moles CO₂.
Thus, 4 moles CO₂ were obtained from the reaction.
Finally, we shall determine the volume occupied by 4 moles CO₂. This can be obtained as follow:
1 mole of CO₂ occupied 22.4 L.
Therefore, 4 moles CO₂ will occupy = 4 × 22.4 = 89.6 L
Thus, 89.6 L of CO₂ were obtained from the reaction.
