what is the mass of a 7.91 cm cubed piece of lead having a density of 11.34 g/cm cubed

Answers

Answer:

The answer is 89.70 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 11.34 g/cm³

volume = 7.91 cm³

We have

mass = 11.34 × 7.91 = 89.6994

We have the final answer as

An orange falls off of a display at a store and rolls 5 meters in 2.5 seconds. What is the average speed of the orange?

Answers

The orange moves at 2M/s
5/2.5=2
2meters/second

An orange falls off of a display at a store and rolls 5 meters in 2.5 seconds the average speed of the orange will be 2 meters per second.

What is speed?

Speed if the rate of change of position of an object in a given time of interval or per unit time of interval and it is the ratio of distance traveled to the time taken and the unit will be meter per second.

The average speed of the orange will be if the orange falls off of a display at a store and rolls 5 meters in 2.5 seconds,

               Speed = distance / time

Substituting the value,

    speed =5 meters /2.5 seconds

    speed = 2 meters per second.

Therefore, the average speed of the orange will be 2 meters per second if, the orange falls off of a display at a store and rolls 5 meters in 2.5 seconds.

What are chemical reaction?

Chemical reaction is defined as a process in which one or more substances, the reactants, are converted into one or more different substances, the products.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

There are five main types of reactions.

Combination reaction - A combination reaction is a reaction in which two or more substance combine to form a single new substance also known as synthesis reaction.Decomposition reaction - A decomposition reaction is a reaction in which a compounds break down into two or more simpler substance.Single replacement reaction - A single replacement reaction is a reaction in which one element replaces a similar element in a compound.Double replacement reaction - A double replacement reaction is a reaction in which the positive or negative ions of to ionic compounds exchange places from two new compound.Combustion reaction - A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of heat and light.

Thus, the chemical formula 3NH4 means there are 3 atoms of nitrogen and 4 atoms of hydrogen in each molecule.

During evaporation, what causes certain liquid molecules to become vapor molecules? A. Decreased fluidity A. Increased viscosity A. Decreased kinetic energy A. Increased kinetic energy.

Answers

Answer:

The answer is A. Decreased Fluidity

Explanation:

Taking the test on preformance matters

In evaporation, particles of liquids take energy in the form of sunlight from the surrounding and then convert into vapor phase. Increased kinetic energy causes certain liquid molecules to become vapor molecules.

What is evaporation?

Evaporation is a physical process in which the water in liquid state converts to gaseous state at the temperature below its boiling point. Evaporation happens before the boiling process.

Evaporation causes cooling effect in the surrounding. During summer when water is kept in earthen pot water cools, this is because of the evaporation process.

Evaporation is affected by temperature. As the temperature increases, kinetic energy of liquid molecules also increases and hence the rate of evaporation increases.

Therefore, increased kinetic energy causes certain liquid molecules to become vapor molecules.

Why are metals in Group 1A so reactive?
A. These metals need one electron to complete their outer shell.
B. These metals need two electrons to complete their outer shell.
C. These metals have one electron in their outer shell.
D. These metals have two electrons in their outer shell.

Answers

Answer:

the answer is = a. these materials...

The metals of Group 1A are so reactive because these metals have one electron in their outer shell. Therefore, option (C) is correct.

What are the metals of Group 1A?

The elements of Group 1A of the periodic table are also called alkali metals. The seven elements of group 1 A include hydrogen(H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

These are low-melting, extremely reactive, glossy metals that oxidize when exposed to air. When dissolved in water, these metals or their oxides produce a basic solution. Because of their high reactivity, alkali metals are instead found as ionic compounds (except hydrogen).

The general electronic configuration of the alkali metals is ns¹. As they lose one electron from their valence shell they acquire the nearest noble gas configuration, therefore they are very reactive.

The alkali metals are all lustrous, soft, and extremely reactive metals at normal temperature and pressure that quickly lose their valence electrons to create cations with charge +1.

According to Dalton’s atomic theory, what are elements and what makes one element different from another?

Answers

Dalton was a chemist who discovered the “law of multiple proportion” in chemical reaction in early nineteenth century. For example, element of tin, he observed, interacted with oxygen to produce two different masses but in proportion 1:2. (Now, this is known to correspond to the formation of tin-monoxide and tin-dioxide, with one and two atoms of oxygen, respectively.)

From such and related studies, he proposed his theory of chemical elements: (a) that all elements are composed of ‘atoms’, the hypothetical indivisible constituents of matter of the ancient Greek thinkers, like, Democritus, and (b) that the elements differ from one another due to the atoms of different masses and sizes that constitute an element.

The modern theory of chemistry says that an element consists of an atom that consists of a heavy nucleus with positively charged ‘protons’ (and most often also the neutral particles called ‘neutrons’) at its center and, an equal number of negatively charged (and much lighter) ‘electrons’, distributed around it in discrete energy shells. Further, the elements differ from one another by the number of positively charged protons in their nucleus, the so-called atomic number, Z, of an atom. Finally, molecules are formed as well as chemical reactions take place, through the exchange or transfer of the electron(s) in the outermost shells of the reacting atoms (and/or molecules).

What is an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
