Answer:
All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.
Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.
Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.
What is the balanced equation for KOH+CO2—>K2CO3+H2O
The balanced equation :
2KOH+CO₂⇒K₂CO₃+H₂O
Further explanationEqualization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
KOH+CO₂⇒K₂CO₃+H₂O
give coeffiecientaKOH+bCO₂⇒K₂CO₃+cH₂O
make equationK, left=a, right=2⇒a=2
H, left=a, right=2c⇒a=2c⇒2=2c⇒c=1
O, left=a+2b, right=3+c⇒a+2b=3+c⇒2+2b=3+1⇒2b=2⇒b=1
the equation becomes :
2KOH+CO₂⇒K₂CO₃+H₂O
Many of the lunar craters are due to volcanic eruptions true or false
Answer:
false
Explanation:
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. ... It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.
In a chemical reaction _________ are the substances present after the reaction?
(PLEASE HELP! I NEED TO GET THIS DONE BY 11:00 PM! SOMEONE TELL ME HOW TO GIVE BRAINILIST BEACAUSE THE PERSON THAT GETS THIS I WILL GIVE BRAINALIST! BUT I DONT KNOW HOW TO SO TELL ME PLEASE! HELPPPPPPPPPPPPPPPP!)
P.S(sorry about the long yelling and again... im in middle school so I am just going to pick chemistry because I don’t know which subject this is, it just says photosynthesis)
Answer:
The substances present after the reaction are called products.
Explanation.
They are called reactants at the start of the reaction.

Compute the number of ions in 58.5 g oh nacl
Answer: Explanation:
58.5 g of Na Cl = 1 mole 5.85 g ofNaCl = 1 X 5.85/58.5 = 0.1 mole Each molecule of NaCI contains one Na ion and one Cl ion = 2 ions Total moles of ions in 0.1 mole of NaCI = 2 x 0.1 = 0.2 moleswhat should we use in soap making process:-
a) potassium hydroxide
b) sodium hydroxide (lye)
Explain why it should be used
Sodium hydroxide, with the formula NaOH, is usually used in products as a pH adjuster. It's also used in soap-making to turn fats and oils into soap. You can find sodium hydroxide (also called caustic soda or lye) in its pure form in the cleaning aisle, since it's also really handy for clearing up clogged drains.

Substance 2 has a stronger molecular attraction.
What are solids?Solid is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.
Both solids are supplied with an equal amount of energy. Out of both substances, substance 2 has a stronger molecular attraction due to which it can not easily change into a liquid while substance 1 has a lesser molecular attraction so supplying of few amounts of heat will change substance 1 into a liquid state.
Hence, Substance 2 has a stronger molecular attraction.

A coffee cup calorimeter contains 153.21 g of water at 22.50 °C. A 65.454 g piece of iron is heated to 101.62 °C. The piece of iron is added to the coffee cup caloriemter and the contents reach thermal equilibrium at 25.68 °C. The specific heat capacity of iron is 0.449 Jg·K and the specific heat capacity of water is 4.184 Jg·K. How much heat, , is lost by the piece of iron?
Answer:
Q = 2232J
Explanation:
In the system, the energy that is lost by the iron is:
Q = S*ΔT*m
Where Q is heat, S is specific heat of iron ΔT is change in temperature and m is mass of the piece of iron.
S = 0.449J/gK
ΔT = 101.62°C - 25.68°C = 75.94°C
m = 65.454g
Q = 0.449J/gK*75.94°C*65.454g
Q = 2232J

6. Which of the following molecules has a central atom with precisely two unshared
pairs of electrons?
methane, CH4
ammonia, NH3
hydrocyanic acid, HCN
water, H20
CLEAR ALL
Answer:
water, H20
Explanation:
From the given choices, only water has two unshared or lone pairs of electrons in its central atom.
The formula of water is:
H₂O
H is hydrogen with 1 electron
O is oxygen with 8 electrons and 6 valence electrons
To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.
The remaining 4 gives the two lone pairs.
