PSYCHO15rus [73]3 years ago
5 0

Answer:

The specific gravity of the rock with respect to water is equal to 3

Explanation:

To solve the question, we list out the variables as follows

Mass of rock = 6 grams

Mass of equal volume of water = 2 grams

Specific gravity or relative density is the mass of a unit volume of a substance divided by the mass of an equal volume of a reference material.

Specific gravity = (mass of substance)/(mass of equal volume of water)

Therefore the specific of the rock sample is = (mass of cube of rock sample)/(mass of same-sized cube of water)

= (6 grams)/(2 grams) = 3

The specific gravity of the rock = 3

From the following balanced equation,
ArbitrLikvidat [17]

Answer:

9.72 grams.

Explanation:

From the equation, 4 moles of NH₃ produce 6 moles of  water.

Therefore the reaction to product ratio of  NH₃ to H₂O is 4:6

and 2:3 into its simplest form.

The number of moles of NH₃ in 6.12 g is:

Number of moles=mass/ RMM

=6.12 g/17 G/mol

=0.36 moles.

Therefore the number of moles of H₂O produced is calculated as follows.

(0.36 Moles×3)2 = 0.54 moles

Mass= Number of moles × RMM

=0.54 moles×18g/mol

=9.72 grams.

What is the complete ionic equation for NaOHaq plus HCIaq equals H2OI plus NaCIaq?
OverLord2011 [107]

Answer:

Ionic equation:

Na⁺(aq) + OH⁻(aq) + H⁺(aq) + Cl⁻(aq)   →  H₂O(l) + Na⁺(aq) + Cl⁻ (aq)

Explanation:

Chemical equation:

NaOH(aq) + HCl(aq)   →  H₂O(l) + NaCl (aq)

Balanced chemical equation:

NaOH(aq) + HCl(aq)   →  H₂O(l) + NaCl (aq)

Ionic equation:

Na⁺(aq) + OH⁻(aq) + H⁺(aq) + Cl⁻(aq)   →  H₂O(l) + Na⁺(aq) + Cl⁻ (aq)

Net ionic equation:

OH⁻(aq) + H⁺(aq)    →  H₂O(l)

The  Cl⁻(aq)  and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
