Answer:

See explanation

Explanation:

When water reacts with formic acid, The following equilibrium is set up;

HCOOH(aq) + H20(l) ⇄ HCOO-(aq) + H30+(aq)

This is because, the water abstracts a proton from formic acid to form its conjugate base, formate ion.

At equilibrium,  the forward is favored.

Ca(s) + O₂(g) + S(s) → CaSO4(s)

The mass of Calcium required to complete this reaction is 4.008 g.

  • Law of conservation of mass states that In a closed system, mass cannot be produced or destroyed, but it can be changed from one form to another.
  • The mass of the chemical constituents before a chemical reaction is equal to the mass of the constituents after the reaction.
  • In several disciplines, including chemistry, mechanics, and fluid dynamics, the idea of mass conservation is widely applied.

In the given reaction mass of product after completion of reaction is 13.614 g that means total mass of constituents before reaction should also be 13.614.

So,

mass of Ca + mass of O₂ + mass of S = mass of CaSO4

Ca + 6.400 g + 3.206 g = 13.614 g

mass of Ca = 13.614 - 9.606 = 4.008 g

Therefore, by law of conservation of mass 4.008 g of Ca is required for the completion of the reaction.

Fill in the missing information:
Neko [114]

Answer: 1. Complete Nuclear Symbol : _{22}^{48}{Ti^{4+}}

2. Atomic number : 22

3. Mass number : 48  

4. Charge : 4 +

Explanation:

Atomic number is equal to the number of protons.

Mass number is the sum of number of neelectrons. utrons and number of protons.

Given : no of protons = 22 , thus atomic number = 22

Mass number =  number of neutrons + number of protons

Mass number =  26 + 22 = 48

Also for a neutral atom , the number of protons is equal to the number of electrons. But here electrons are 4 less than protons, which means the atom has lost 4 electrons and thus will have a charge of 4+.

The atomic number is specific to an element, and the element with atomic number 22 is Titanium (Ti). The representation is _{22}^{48}{Ti^{4+}}

Boron<br> B<br> 10.811<br> Number of neutrons
andrew-mc [135]

Answer:

6

Explanation:

To determine the number of neutrons we round 10.8 to 11 and subtract the atomic number (5) and get 6; therefore, boron has 6 neutrons.
