Answer: well our digestive system is very sensitive so when you chug a drink to fast or you eat way to fast, it causes your diaprgam to go in and out fast flexing, so it’s causes us to hiccup.

it is also the same for as when we breath

Explanation:

This problem deals with balancing of chemical equations.

Every chemical equations obey the law of conservation of matter which states that "in chemical reactions, matter is usually conserved and are not produced, they are simply recombined".

Equation of reaction:

BaO₂ + H₂SO₄ ⇒ H₂O₂ + BaSO₄

Let us use a mathematical approach to balance this equation by setting up simple algebraic equations:

aBaO₂ + bH₂SO₄ ⇒ cH₂O₂ + dBaSO₄

a, b, c and d are the number of moles that will balance the equation;

Conserving Ba: a = d

O: 2a + 4b = 2c + 4d

H: 2b = 2c

S: b = d

now let a = 1

d = 1

b = 1

c = 1

we see that the equation is already balanced

In the reaction BaCO3 + 2HNO3 + Ba(NO3)2 + CO2 + H2O, what mass of Ba(NO3)2 can be formed by combining 55 g BaCO3 and 26 g HNO3

Nataliya [291]

From the stoichiometry of the reaction, the mass of barium nitrate produced is 54.9 g.

<h3>Stoichiometry</h3>

The term stoichiometry refers to mass - volume relationships. Stoichiometry can be used to calculate the amount, mass or volume of reactants and products from the balanced reaction equation.

The equation of the reaction is written as follows;

BaCO3 + 2HNO3 ------> Ba(NO3)2 + CO2 + H2O

Number of moles of BaCO3 = 55 g/197.34 g/mol = 0.28 moles

Number of moles of HNO3 = 26 g/63.01 g/mol = 0.41 moles

From the reaction equation;

1 mole of BaCO3 reacts with 2 moles of HNO3

0.28 moles of BaCO3 reacts with 0.28 moles × 2 moles/1 mole = 0.56 moles

There is not enough HNO3 hence it is the limiting reactant.

Number of moles of Ba(NO3)2 produced is obtained from;

2 moles of HNO3 yields 1 mole of Ba(NO3)2

0.41 moles of HNO3 yields 0.41 moles × 1 mole/2 moles

= 0.21 moles of Ba(NO3)2

Mass of Ba(NO3)2 = 0.21 moles × 261.337 g/mol = 54.9 g

G We've all blown up balloons. When you blow into a balloon, you are putting in more moles of gas. Let's say that on the second exhalation (blow) you blow in the exact same number of moles as you did with the first exhalation. So, you doubled the number of moles in the balloon. If the temperature and pressure remained constant, what is true about the volume of the gas in the balloon
