The chemical reaction is balanced.
Explanation:
We have the following chemical reaction:
NaOH + HCl → NaCl + H₂O
It is a neutralization reaction between a base and an acid which produce a salt and water.
To balance the chemical reaction the number and type of atoms entering the reaction have to be equal to the number and type of atoms leaving the reaction. We do that to conserve the mass.
We do not need to add other stoechiometric coefficients because the reaction is already balanced.
1 Na atom is entering the reaction and 1 Na atom is leaving the reaction
1 Cl atom is entering the reaction and 1 Cl is leaving the reaction
1 O atom is entering the reaction and 1 O atom is leaving the reaction
2 H atoms are entering the reaction and 2 H atoms are leaving the reaction

Answer:
8 moles of C
Explanation:
From the question given above, the following equation was obtained:
3A + 2B —> 6C
From the equation above,
3 moles of A reacted to produce 6 moles of C.
Thus, the number of mole of C produced by reacting 4 moles of A can be obtained as follow:
From the equation above,
3 moles of A reacted to produce 6 moles of C.
Therefore, 4 moles of C will react to produce = (4 × 6)/3 = 8 moles of C
Thus, 8 moles of C can be obtained from the reaction of 4 moles of A with excess B
Answer:
1.3g/L is the density of the air
Explanation:
The room is full of air, the space that the air occupy is:
500 cm x 400 cm x 250 cm = 5.00x10⁷ cm³
The density of a substance is defined as the ratio between the mass of the substance and the space that occupy. We can express the density of air in g/L:
<em>Grams air:</em>
65 kg * (1000g / 1kg) = 65000g
<em>Liters:</em>
5.00x10⁷ cm³ * (1L / 1000cm³) = 50000L
<em>Density:</em>
65000g / 50000L =
<h3>1.3g/L is the density of the air </h3>
Answer:
Middle: Self heating containers are really expensive but are useful because they are easy to use, portable, and can be recycled, unlike a camp stove which is not as easily moved.

<u>Answer:</u>
<em>Indonesia Bank one of the largest consumers of electricity or energy in any form depends on fossil fuels for energy.</em>
<u>Explanation:</u>
Utilisation of solar energy for their day to day basis such that the energy need is met would mean less use of fossil fuels and lesser greenhouse gases.
And also damage to the environment and this is a very important step by Indonesia to do their bit towards environment by controlling pollution and being largest consumer turning green would mean a lot.
