Answer:
LIQUID
Explanation:
The substance found to change shape in a different container but maintained volume is most likely a liquid.
STATE OF MATTER:Matter is any substance that has weight and occupies space. Matter can exist in three different states namely:
SolidLiquidGaseousLiquid as a state of matter is characterized by weak bonds that holds its particles together, hence, liquids flow.
Liquids assume the shape of the container that holds them. Hence, according to this question, the substance found to change shape in a different container but maintained volume (50ml) is most likely a liquid.

what is balance equation and how we balance equation
Answer:
To adjust the substance condition, you need to ensure the quantity of molecules of every component on the reactant side is equivalent to the quantity of particles of every component on the item side. To make the two sides equivalent, you should duplicate the quantity of particles in every component until the two sides are equivalent.

If I use warm water on my plants then they will grow faster as hot water increases metabolism." This is an example of
Question 1 options:
a hypothesis
a theory
a research question
a scientific explanation
Answer:
a hypothesis
Explanation:
A hypothesis is a statement that is supposed or assumed before conducting any experiment. It is the assumption that is made on the basis of certain knowledge and controlled evidence in the initial time of the experiment. The initial assumption helps in taking the experiment or the investigation further. The truth is not ascertained in the initial phase rather the completion of the investigation is necessary to make a hypothesis turn into a theory.
In the given situation, the statement given is a hypothesis because the use of the warm water for the growth of the plants is the assumption made with respect to the metabolism effect on the humans.

How many moles of sodium hydroxide, NaOH, are in a 35.65 g sample
of NaOH? (The molar mass of NaOH is 40.01 g/mol.)
Answer:
0.8910 mols of NaOH in a 35.65 g sample of NaOH
Explanation:
Mass off NaOH = 39.997
given = 35.65 g of NaOH
35.65 g of NaOH * 1 mol NaOH = 0.8910, since there are 4 sig figs.
/40.01 g
A 35.65 g sample of NaOH contains 0.8910 moles of NaOH.
What is mole?The mole, denoted by the sign "mol," is the volume of a system that has the same number of atoms in 0.012 kilograms of carbon-12 as there are elementary particles.
The mole, often known as mol, is a SI unit used to measure how many particles are present in a given substance. A mole is made up of 6.02214179 atoms or other fundamental building blocks like molecules.
Mass off NaOH = 39.997
given = 35.65 g of NaOH
No of moles of NaOH =35.65 g of NaOH × 1 mol NaOH /40.01 g
No of moles of NaOH = 0.8910 moles.

What type of energy results from the burning of wood or gasoline?
electric
nuclear
chemical
Answer:Electric
Explanation: Its right.
Chemical energy results from the burning of wood or gasoline. Therefore, option (C) is correct.
What is chemical energy?Chemical energy is described as the energy which is stored in the chemical bonds formed in the chemical compounds. It is liberated during the chemical reaction and produces heat as a side-product which is known as an exothermic reaction.
Examples of chemical energy are biomass, natural gas, batteries, petroleum, and coal. When chemical energy is released from a compound, it is transformed into a completely new substance.
While burning wood or fuel, the chemical energy in the wood or gasoline is liberated as heat because of the chemical reaction of oxygen in the air and wood. This kind of chemical reaction is known as a combustion reaction. Combustion reaction converts the chemical energy stored in the wood into light energy and heat.
Therefore, in the burning of wood or gasoline, chemical energy is emitted.

How much will it cost in American dollars(USD) to fill a 15 gallon tank of gasoline in Canada, if the price of gasoline there is $1.07 Canadian dollars (CAD) per liter. The current exchange rate is ($1.00(USD)= $1.34(CAD), 1 L=1.06 qts, 1.61 Km= 1 Mile, 1 gal= 4 qts]
Answer:
It will cost 45.37 US dollars (USD) to fill a 15 gallon gas tank in Canada.
Explanation:
Two values are directly proportional when when one value increases, the other increases in the same proportion, or when one value decreases, the other decreases in the same proportion.
The rule of three makes it possible to solve proportionality problems effectively and quickly. It is a method of calculating an unknown value that is directly proportional to another known value.
Then, knowing the data a, b and c, and the fourth unknown data x, which will be the unknown to be solved, this value is calculated as:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{c*b}{a}[/tex]
You must calculate the cost in US dollars (USD) to fill a 15 gallon gas tank in Canada. You know that the price of gasoline is $1.07 Canadian dollars (CAD) per liter. If 1 L equals 1.06 qts, then you can say that the price of gasoline is $ 1.07 Canadian dollars (CAD) per 1.06 qts.
You can now apply a rule of three as follows: if 4 qts is equal to 1 gal, 1.06 qts is equal to how much gal is?
[tex]gal=\frac{1.06 qts*1 gal}{4 qts}[/tex]
gal= 0.265
Then you can say that the price of gasoline is $ 1.07 Canadian dollars (CAD) per 0.265 gal. So you can apply the following rule of three: if 0.265 gal costs $ 1.07 Canadian dollars (CAD), 15 gal how many Canadian dollars cost?
[tex]CAD=\frac{15 gal*1.07 CAD}{0.265 gal}[/tex]
CAD= $60.8 CAD
Finally, you can apply the following rule of three: if $ 1.34 (CAD) is equal to $ 1.00 (USD), $ 60.8 (CAD) is equal to how many US dollars (USD)?
[tex]USD=\frac{60.8 CAD*1USD}{1.34 CAD}[/tex]
USD= 45.37
It will cost 45.37 US dollars (USD) to fill a 15 gallon gas tank in Canada.

calculate the number of molecules in 52 gram of helium
Answer:
The molar mass that is the mass of 6.022 X 1023 atoms of helium is 4g. Hence 1 mole of He = 4 g of He = 6.022 X 1023atoms of He.
1 g of He = (6.022 X 1023) / 4 atoms of He.
52 g of He = (6.022 X 1023X 52 ) / 4 atoms of He.

The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
