Hope this helps!
First you would melt because the melting point for ice is 0c. Then you would become warmer and warmer as the temperature rises. Lastly once the temperature reaches 100c you'll begin to evaporate as the boiling point for water is 100c.
Answer:
Explanation:
Net force F = 1800 N
acceleration a = 1.5 m /s²
mass = m
mass = force / acceleration
= 1800 / 1.5
m = 1200 kg
Answer: C. The non metal
Explanation:-
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The nomenclature of ionic compounds is given by:
1. Positive ion or metal is written first.
2. The negative ion or non metal is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
For example:
, cesium is metal having an oxidation state of +1 called as
cation and bromine
is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
called as cesium bromide.
Answer:
4.25g
Explanation:
Molar concentration or molarity can be calculated thus;
Molarity (M) = number of moles (n) ÷ volume (V)
According to the provided information in this question, Volume = 5.0L, M = 0.050 M
number of moles = molarity × volume
n = 0.050 × 5
n = 0.25moles
Number of moles in a substance = mass (M) ÷ molar mass (MM)
Molar mass of ammonia (NH3) = 14 + 1(3)
= 17g/mol
Mass = moles × molar mass
Mass (g) = 0.25 × 17
Mass = 4.25g
