Answers

Answer 1

Answer:

There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Therefore, the correct option is option A.

What is periodic table?

Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.

Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can discover the new elements that are not being discovered yet.

Within a period, an increase in atomic number is usually accompanied by a decrease in atomic radius and an increase in electronegativity.

Therefore, the correct option is option A that is a decrease in atomic radius and an increase in electronegativity.

In the chemical reaction in which sucrose is heated and decomposes to form carbon dioxide and water, which of the following is a reactant?a. sucrose
c. water
b. carbon dioxide
d. heat

Answers

A reaction in which the reactants splits to produce two or more products is called a decomposition reaction.

It can be represented as:

XY ------> X + Y

The correct answer is:

Option A. Sucrose

This can be explained as:

The reaction for the decomposition of sucrose is given as:

C₁₂H₂₂O₁₁ (Sucrose) + 12 O₂ -----> 12 CO₂ (Carbon dioxide) + 11 H₂O (water)

The reactant of a reaction is written generally on the left side of the reaction.

The reactant is a substance that reacts and undergoes chemical changes to form products.

Therefore, sucrose is the reactant.

object a at 40 degrees C and object b at 80 degrees C are placed in contact with each other which statement descibes the heat flow between the objects

Answers

Object A at 40 degrees C and object B at 80 degrees C are placed in contact with each other. The heat flow will flow from the Object B to the object A because of temperature difference. To attain equilibrium, the heat flow must flow form a higher temperature to a lower temperature.

a block of iron has the dimensions of 3.00 cm x 3.00 cm x 3.00 cm. it has a mass of 213 g. what is its density? a. 638 g/cm3 b. 6240 g/cm3 c. 0.0773 g/cm3 d. 7.89 g/cm3

Answers

Volume = 3 cm × 3cm × 3cm
= 27 cm ³

Mass = 213 g

Density = $(MASS)/(VOLUME)$

= $(213 g)/(27 cm ^(3) )$

= 7.89 g / cm³

Thus answer is D.

Find the product.
(n + 8)(n - 2)
n2- 6n - 16
n2+ 6n - 16
n2- 6n + 16

Answers

Answer:The product of the given expression is : $n^2+6n-16$

Explanation:

Given expression:(n + 8)(n - 2)

Using identity: $(a+b)(a+c)=a^2+(b+c)a+bc$

a = n, b=8, c= (-2)

$n^2+(8+(-2))n+(8)(-2)$

$n^2+6n-16$

The product of the given expression is : $n^2+6n-16$

Answer : The product of the given expression is:

$n^2+6n-16$

Explanation :

The given expression is:

$(n+8)(n-2)$

First we have to open the bracket by multiplying the terms.

$n^2-2n+8n-16$

Now we are adding like terms.

$n^2+6n-16$

Hence, the product of the given expression is, $n^2+6n-16$

8.00*10^-5 mol was diluted to 500ml what is the concentration in Mol/L?

Answers

Make sure all units are consistent. Convert ml to L first. (500ml = 0.5L). Then divide the mole by the volume which would result to 1.6*10^-4mol/L. This can also be expressed as interms of molarity (M). 1 M = 1 mol/L hence the final answer is 1.6*10^-4 M.

Answer : The concentration in mol/L is $1.6* 10^(-4)mol/L$
