what is the density of a 100g piece of titanium if a 10g piece of titanium has a density of 4.506g/cm3?

Possible answers:
A: 45.06g/cm3
B:4.506g/cm3
C: 9.1g/cm3
D: 91g/cm3

Answers

Answer:

B. Density stays the same no matter how much of a substance there is.

Explanation:

Density of the substance is the same and it is the measure of its mass per unit volume. Thus, the mass of titanium per  1 cm³  is 4.506 g which is the same for 10 g, 100 g or whatever the mass.

What is density ?

Density of a substance is the measure of its mass per unit volume. It describes how closely its particles are packed.  Density of an object depends on its bond type, temperature and pressure.

The more denser the object is , more will be its mass distribution per unit volume. Substances denser than water will sink on it otherwise they float on water.

Density is constant for a substance, the distribution of given mass per unit volume is same for all masses. Hence, the density of 100 g Ti is same as that of 10 g. i.e., 4.56 g/cm³.

what is inert pair effect​

Answers

Answer:

The inert pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals. The term inert pair effect is often used in relation to the increasing stability of oxidation states that are two less than the group valency for the heavier elements of groups 13, 14, 15 and 16. .[1] The name suggests that the outermost s electrons are more tightly bound to the nucleus in these atoms, and therefore more difficult to ionize or share

In your own words, please explain how to name acids.

Answers

Answer:

Acids are named based on their anion — the ion attached to the hydrogen. In simple binary acids, one ion is attached to hydrogen. Names for such acids consist of the prefix “hydro-“, the first syllable of the anion, and the suffix “-ic”. Complex acid compounds have oxygen in them.

a solid sample of oil until it turns an iquid. which property of the oil will decrase?

Answers

Answer:

Density of the oil

Explanation:

As the oil sample is warmed and it turns liquid, the density of oil will decrease due to increase in volume of the oil.

Warming of the oil increases the volume of oil as it melts. The once solid oil becomes more mobile and takes up more space. Although the mass is the same. Since volume increases, the density of the oil will reduce because, density is the mass per unit volume of a substance.

Solute is substance which is dissolve in a solvent and Solvent is a substance that dissolves solute in a solution.
Answer: Solute is the substance being dissolved, and solvent is the substance that the solute is dissolving in. For example, 1 g of sugar in 100 mL of water. Sugar is being solved so it is the solute, and water is what the sugar is dissolving in so it is the solvent.

10 g of copper is heated and the mass increases to 12.5 g. What is the mass of the copper in the new substances?

Answers

Answer:

10g

Explanation:

The amount of copper in the heated mass of the new substance produced is still 10g because in any chemical action, mass is always conserved.

According to the law of conservation of matter "matter is neither created nor destroyed in a chemical reaction". The change in mass is only due to oxygen gas that combines with the new copper formed or other substances that joined the mass. The substance will still have the same amount of copper as the original one. Since we started with 10g of copper, we end with 10g of copper.

How many moles of NaCl could be found in 0.4 L of a 0.9 M solution? Round your answer to
two decimal places.

Answers

Answer:

0.36mol

Explanation:

Given parameters:

Volume of NaCl  = 0.4L

Molarity  = 0.9M

Unknown:

Number of moles  = ?

Solution:

To find the number of moles, the molarity of a solution is the amount of solute contained in a solution.

 Molarity  = [tex]\frac{number of moles}{volume}[/tex]  

 Number of moles = molarity x volume

 Insert the parameters and solve;

 Number of moles = 0.4 x 0.9  = 0.36mol

When you climb to the top of a water slide, you are gaining:
O A. gravitational kinetic energy.
B. chemical potential energy.
c. gravitational potential energy.
D. chemical kinetic energy.

Answers

Answer:

C

Explanation:

You climbing the water slide gives you potential energy and your building gravitational eneergy.

When we climb the top of a water slide we are gaining gravitational kinetic energy. That is we are moving through the surface and thus we experience both kinetic energy and gravitational energy.

What is  kinetic energy?

Kinetic energy of a body is generated by virtue of its motion. Gravitational energy is a form of energy by which the an object attracts other object to its center of mass. Both forms of energy are  directly proportional to the mass of the object.

Potential energy is generated by virtue of  the position and height of the object. As the height from surface increases, potential energy increases. Potential energy and kinetic energy together called as mechanical energy of an object.

When starts moving our potential energy is converting to kinetic energy. Hence, when we climb the top of a water slide kinetic energy starts to increase. Thus, option A is correct.
