D. Temperatures of the solvent and solute

This question is incomplete because the options are missing; here are the options:

Which of the following is LESS dense than water?

The spoon

The glass

The tablets

The bubbles

The correct answer to this question is The bubbles

Explanation:

In general, the density of materials and substances affects their buoyancy. This implies in water less dense materials will float and those with higher density will sink. In the situation presented, the only element that is less dense than water are bubbles; this is shown by the movement of the bubbles as these originate in the bottom of the glass of water but they rise to the surface, which shows they are less dense than water.

Answer:

the bubbles

Explanation:

which is 1.26 x 1024 calculating with avogardos law

Answer:

1.26 X 1024 molecules

Explanation:

The question is incomplete, the complete question is;

One tank of goldfish is feed the normal amount which is once a day, a second tank is fed twice a day, and a third tank is fed four times a day during a 6 week study. The fishes' body fat is recorded daily.

Independent Variable-

Dependent Variable-

Constants

Control Group-

Answer:

A) The amount of food the gold fish receives

B) Body fat of the gold fish

C) -Type of fish used in the study (gold fish)

Time period within which the fishes were fed (Six week period)

Shape and size of tank

D) group of gold fish fed the normal amount

Explanation:

The purpose of the study is to determined the impact of amount of feed on the body fat of gold fish. Hence, the amount of feed is the independent variable while the body fat of the feed is the dependent variable.

The control group receives the normal amount of feed (once a day). The fishes are all gold fish, fed within a six week period. All the tanks were of the same shape and size. These are the constants in the study.

Answer:

Whats the question lolzzzz

Explanation:

Answer:

1 .  2.393e+ 9

2. ???

3. 3.25e-6

Explanation:

2393 kg = 2.393e+9 mg

43.23 g = 4.323 dam

0.325 cm = 3.25e-6 km

(Note: I'm not 100% that these are correct, but I hope this helps you tho. ^^)

Answer:

Don't mark me brainliest because of this but I'm pretty sure your supposed to give us the words because teachers don't give you things like that without the words you will the answer in with.

Answer:

Same as number of NUETRONS

POSITIVE charge

number of protons is the same as the atomic NUMBER

Located in the Nucleus

Larger mass than ELECTRONS

Explanation:

GOOD LUCK

Answer:

1.33

Explanation:

sorry if im wrong :(

Answer:

argon

Explanation:

Answer:

Argon

Explanation:

Answer: Here u go!

Explanation:

In other words, "K"^(+) has bigger effective nuclear charge than "Cl"^(-), which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius.

Hope this helps ma dude!

Answer:

Hof(X) = - 1474.9 KJ/mol

Explanation:

The reaction equation given to us is:

2 X + 5 O2 (g) --> 4 CO2 (g) + 6 H2O (g) ∆H = -75.0 kJ

Now, the equation for the standard enthalpy of formation of the reaction is written as follows:

ΔH = 4*Hof(CO2(g)) + 6*Hof(H2O(g)) - 2*Hof(X) - 5*Hof(O2(g))

where,

ΔH = - 75 KJ

Hof(CO2(g)) = Standard Heat of Formation of CO2(g) = -393.5 KJ/mol

Hof(H2O(g)) = Standard Heat of Formation of H2O(g) = -241.8 KJ/mol

Hof(X) = Standard Heat of Formation of X = ?

Hof(O2(g)) = Standard Heat of Formation of O2(g) = 0 KJ/mol

Therefore,

-75 KJ = (4)(-393.5 KJ/mol)+ (6)(-241.8 KJ/mol) - (2)(Hof (X)) - (5)(0 KJ/mol)

- 75 KJ + 3024.8 KJ = - (2)(Hof(X))

Hof(X) = -2949.8 KJ/2 mol

Hof(X) = - 1474.9 KJ/mol

Answer:

Gravity

Explanation:

Gravity is the pull of an object to another object like a human to the Earth. This is weight.

Answer:

C. Gravity

Explanation:

Just Took The Test And Got A Perfect Score. ;)

Answer:

(Ge)

Explanation:

I'm just taking a wild guess really!

Answer:

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.

Answer:

Metals typically loose electrons and become cations

Explanation:

Metals are typically found towards the left hand side of the periodic table. They typically possess fewer electrons in their outermost shell compared to nonmetals.

As a result of this, when metals form chemical bonds with other elements, it is energetically more favourable for metals to loose electrons and form cations.
