Write down the answer. Make sure to use the correct number of sig figs or
spots after the decimal. 987.22 - 377.1*

Answers

Answer:

610.1

Explanation:

When we add or subtract the values, the number of significant figures after decimal in result must be equal to the given measurement having less number of decimal places.

In given values 377.1 has only decimal place thus in result after decimal there should be one digit only.

987.22 - 377.1 = 610.1

When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.

Now we will calculate the difference between 7.69 and 4.0.

7.69 - 4.0 = 3.69

In given values 4.0 have less number of significant figures thus result must have only two significant figures . So we would round the result.

O2 are mixed together, and the above reaction goes to completion?

Answers

Answer:

4.00 moles of water

Explanation:

The equation of the reaction is:

2 C2H2Cl (9) + 5O2(g) -------> 4CO2 (g) + 2 H20( g) + 2 HCl(g)

To find the limiting reactant,  we find the species that yields the lowest number of moles of water.

From the reaction equation;

2 moles of C2H2Cl  yields 2 moles of water

10 moles of C2H2Cl  yields 10 * 2/2 = 10 moles of water

Similarly;

5 moles of oxygen yields 2 moles of water

10 moles of oxygen will yield 10 *2/5 =4 moles of water

Hence oxygen is the limiting reactant.

10 moles of oxygen yields 4 moles of water.

A hypothetical element has two main isotopes with mass numbers of 59 and 62. If 73.00% of the isotopes have a mass number of 59 amu, what atomic weight should be listed on the periodic table for this element? Answer in units of amu.

Answers

since 73% of the isotope is given, take 100%-73% to get the remaining % of the isotopes which is going to be 27%.

hence,

atomic weight= (73×59) + (27×62)

=4307+1302

=5609 amu

Answer:

The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1". In general it is known that nonmetals are very poor conductors of heat and electricity. The nonmetals that are solid are normally very brittle and has very little or no metallic luster at all. Nonmetals are highly reactive and show variety of chemical properties. It can also be pointed out that the nonmetals gain electrons very easily.

Answers

Given : Density of Bromine = 3.12 g/mL
Formula : Density = Mass / Volume

Part A :
Given Volume = 125 mL
Density = Mass / Volume
So, Mass = Density x Volume
= 3.12 x 125
= 390 grams

Part B :
Given mass = 85.0 gm
Density = Mass / Volume
So, Volume = Mass / Density
= 85 / 3.12

Calculate the average atomic mass of unknown element X. You determine that isotope 127X makes up 80%, isotope 126X makes up 17%, and isotope 128X makes up 3%.

A. 127.10 amu
B. 126.86 amu
C. 127.54 amu
D. 126.20 amu

Answers

Answer:

Option B. 126.68 amu

Explanation:

The following data were obtained from the question:

Isotope A (¹²⁷X):

Mass of A = 127

Abundance (A%) = 80%

Isotope B (¹²⁶X):

Mass of B = 126

Abundance (B%) = 17%

Isotope C (¹²⁸X):

Mass of C = 128

Abundance (C%) = 3%

Average atomic mass of element X =.?

Th4 average atomic mass of X can be obtained as follow:

Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

= [(127 × 80)/100] + [(126 × 17)/100] + [(128 × 3)/100]

= 101.6 + 21.42 + 3.84

= 126.68 amu

Therefore, the average atomic mass of X is 126.68 amu
