(a)
(b)
(d)
Answer:
it is option A hope it helps
The properties of nonmetallic oxides include acidity and covalent character. Hence, option A is correct.
What are non-metals?Non - metals are elements in the rightmost side of the periodic table. Non -metals are mostly gases and some of them include, metalloids also. Non-metals are commonly electron -deficient and some of them are highly electronegative.
A compound shows covalent character, if the electrons are shared between the constituent atoms. Covalency increases from left to right in periodic table.
As the covalent character increases, acidity increases. Oxides of non-metals are electrophiles and acts as Lewis acids. They are all covalent compounds. Therefore, option A is correct.

why do non-metal aroms form covalent bonds e.g. H2O
Answer:
Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. ... Covalent compounds tend to be soft, and have relatively low melting and boiling points.

Answer:
The least similar to a real gas found in the environment would be B.
Explanation:
Standard Ambient Temperature/Pressure (SATP) is at 298.15K and 101.3kPa. It describes standard conditions and is often used for measuring gas density and volume using the Ideal Gas Law. The values least similar to theses ones would be the least similar in the gases in the environment.
For the reaction H2 + O2→ H2O, how many grams of water are produced from 6.00 mol of hydrogen?
Answer:
108 g
Explanation:
2H₂ + O₂ ⇒ 2H₂O
1) n(H₂) : n(H₂O) = 2 : 2
Hence, n(H₂O) = n(H₂) = 6,00 mol
2) m(H₂O) = n × M = 6,00 mol × (2 + 16) g/mol = 6,00 × 18 mol = 108 g
By counting the number of crests that pass by a given point in a set amount of time, what you would be calculating?
Answer:
Frequency
Explanation:
When we talk about crests, we are referring to the high points of a wave.
We measure wave frequency by counting out the the number of crests (or high points) of a given wave that pass by a given point in a set amount of time. Thus, the higher the number of crests, the greater the frequency of the wave and vice versa.
We define the frequency of a wave as the number of waves that passes by a fixed point within a given period of time.

Answer:
Exothermic
Explanation:
The equation of the reaction is given as;
H₂O(vapour) --> H₂O(liquid)
The equation above represents a condensation process. Water vapour condenses to liquid.
Condensation involves loss of energy as heat. The equation can be modifies as;
H₂O(vapour) --> H₂O(liquid) + Heat
Due to the loss of heat, condensation is regarded mas an exotheric process.

ammonia gas cannot be collected in an erect gas jar?why?
Answer:
ammonia being lighter than air, is collected by downward displacement of air in an inverted gasjar
The gas jar is used to collect ammonia gas. This gas can be barely dissolved in water. As a result, the downward displacement of water does not gather it in the jar.
What is ammonia ?With the formula NH3, ammonia is a nitrogen and hydrogen inorganic chemical. Ammonia, the simplest pnictogen hydride and a stable binary hydride, is a colorless gas with a strong, pungent odor.
Because it is simpler to install inlets and outlets in one end of an erect gas jar than it is to install them on the side or the bottom, which are required for placement on a stable surface.
Ammonia is prepared in a laboratory by forcing air downward to collect the gas. Due to the high solubility of ammonia in water, it is impossible to collect ammonia gas over water.
Thus, The gas jar is used to collect ammonia gas.

2 eggs cook in a frying pan, which is sitting over a gas burner.
Is thermal energy being transferred by radiation in this image? Why or why not?
Answer:
No, thermal energy is not being transferred by radiation. The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame, so this is conduction, not radiation. Radiation transfers thermal energy by electromagnetic waves, not by direct contact.
Answer:
no
Explanation:
a metal pan is cooking the eggs because the flame is touching the pan and the molecules are colliding with each other
