Which coefficient is needed in front of NaNO3 to balance the equation Na2S + Zn(NO3)2 – ZnS + _NaNO3?
O 1
O 2
O 5
O 7
Answer:
A.1
Explanation:
The coefficient needed in front of NaNO₃ to balance the equation
Na₂S+ Zn(NO₃)₂---->ZnS + NaNO₃ is 2, therefore option (b) is correct.
What do you mean by the balanced chemical equation ?A balanced chemical equation is an equation that has equal numbers of atoms for each element both on the reactant and product sides.
Methods to balance the chemical equation -:
The number of atoms for a given element is calculated by multiplying its coefficient with the element’s subscript in its chemical formula.
The coefficients in front of the formulas to show how many molecules of that material are used or produced.
Hence, the coefficient needed in front of NaNO₃ to balance the equation
Na₂S+ Zn(NO₃)₂---->ZnS + NaNO₃ is 2, therefore option (b) is correct.

An atom can be called a particle, but a molecule is never called a particle. True or False ?
Answer: False; it contains particles, but that doesn't mean it's a particle itself.
Hope this help.
The statement is false, both atoms and molecules could be referred to as particles.
An atom is defined as the smallest particle of a substance that can take part in a chemical reaction.
An atom is the smallest particle of a an elemental substance while a molecule is the smallest particle of a compound. Compounds are made up of molecules which are neutral particles.
The main difference between an atom and a molecule is that a molecule is a group of atoms held together by a chemical bond while atoms just occur individually.

The graphs below show the change in temperature and salinity of a region of ocean as a instrument is lowered below the surface. Depth is measured in kilometers below the surface, temperature in degree Celsius, and salinity in parts per thousand.
Which prediction is most likely, based on the data?
Answers:
A) In the ocean, as salinity increases, temperature increases.
B) Organisms that require a steady salinity move freely between sea level and -0.4 km.
C) Ocean salinity decreases at depths greater than -1.8 km below the surface.
D) Organisms that require a temperature at 5 degrees C will thrive -0.6 km below the surface.
The most likely prediction based on the data is 'organisms that require a steady salinity move freely between sea level and -0.4 km' (Option B).
Salinity conditions refer to the concentration of dissolved salts in an aqueous medium.Salinity conditions may alter the physiological features of an organism, as well as its metabolic pathways (e.g., behavior, reproduction, motion).The changes in salinity can negatively alter the evolutionary fitness of an organism and its survival in particular environmental conditions (in this case, steady salinity allows organisms to move freely).In conclusion, the most likely prediction based on the data is 'organisms that require a steady salinity move freely between sea level and -0.4 km' (Option B).

During which phase does Earth see more than half of the moon's surface? first quarter third quarter waxing gibbous waning crescent
A: Frist quarter
b: third quarter
c: waxing gibbous
d: waning crescent
Answer:
c
Explanation:
During the "Third Quarter" phase, Earth sees more than half of the moon's surface. The correct option is B.
What is Waxing Gibbous and Waning Crescent?Waxing Gibbous and Waning Crescent are two phases of the Moon.
Waxing Gibbous is a phase of the Moon that occurs after the First Quarter phase and before the Full Moon phase. During this phase, the illuminated portion of the Moon is greater than half but less than fully illuminated, meaning it appears to be a "bulging" shape. The term "waxing" means that the illuminated portion of the Moon is increasing in size.
The Waning Crescent is a phase of the Moon that occurs after the Third Quarter phase and before the New Moon phase. During this phase, the illuminated portion of the Moon is less than half and decreasing in size. The term "waning" means that the illuminated portion of the Moon is decreasing in size. The crescent shape refers to the thin sliver of illuminated portion of the Moon that is visible during this phase.
Here in this question,
During the First Quarter phase, the right half of the Moon's surface is visible from Earth.
During the Third Quarter phase, the left half of the Moon's surface is visible from Earth.
During the Waxing Gibbous phase, more than half of the Moon's surface is visible, but Earth does not see more than half.
During the Waning Crescent phase, less than half of the Moon's surface is visible, and Earth does not see more than half.
Therefore, Option B i.e third quarter is correct.

Chlorine is a very reactive non-metals. Why
Answer:
Chlorine is a very reactive non metals because this element don't form any known chemical compound.
Explanation:
Chlorine atoms have a lot of valance electrons without being complete on its own, so it has a greater need to seek it's conjugates. That's called electronegativity. Halogens are highly reactive because of their electronegativity.
