Being frozen, staying a liquid, becoming ice, and becoming a gas (steam)
Answer:
ionic
Explanation:
In NH4Cl molecule, ionic bond is formed between NH4+ and Cl– ions, 3 covalent bonds are formed between N and three H atoms and one coordinate bond is formed between N and 1 H atom.

Answer:
Volumes can have the same volume but different masses if they have different densities. For example, a 10 x 10 x 10 block of lead has the same volume as a 10 x 10 x 10 block of pine wood, but the lead block weighs 22.6 times more than the pine block. Indeed, the density of lead is high enough that the lead block will sink in water, whereas the pine block's density is low enough that the pine block will float in water.
Volume is a measurement, the units are cubic metres or cubic centimetres. Litres = 1000 cm3
Mass is a measurement, the units are grams, kilograms.
^^^^^^^^^^^^^^^^^^
to that answer.
Mass is not weight. it is the amount of matter an object takes up. Therefore, saying that a lead block weights 22.6 times more than the pine block does not answer how an object can have different masses but the same volume. :D

Explanation:

The block will sink
Explanation:
In general, an object with a higher density than water will sink in it, and one with a lower density will float. Now, to know if the block will float or sink, the first step is to calculate the density of the block, and to do this, the volume and mass of the block are required.
Mass of the block: 30 grames
Volume of the block:
The volume of the block is not provided, but this can be found using the dimensions given.
V (Volume) = s (side) x s x s
V = 1.5 cm x 4.8 cm x 2.3 cm
V = 16.56 
Density of the block:
To find the density simply divide the mass into the volume
D (density) = M (Mass) ÷ V (Volume)
D = 30 grams ÷ 16.56
D = 1. 811 grams/
The density of the block is 1. 811 grams/
Additionally, the density of the water is 1 gram/ or 1 gram/mL. According to this, the density of the block is higher than the density of the water, and therefore this is the block sinks.
