The balance that can be used to measure a mass reading of 0.90 g will be a balance with ±0.01 g tolerance.

The mass reading balance used for measurement

1.230 g ±0.001 g tolerance

5.43g ±0.01 g tolerance

4.0000g ±0.0001 g tolerance

6.539g ±0.001 g tolerance

<h3>What is the tolerance of a balance?</h3>

The tolerance of a balance is the number of decimal place values shown on the balance and it is the permissible limitations measured in grams, that a balance can tolerate.

Hence, depending on the decimal place value behind a mass reading will determine the balance used for measurement.

From the given parameters:

The mass reading balance used for measurement

0.90 g ±0.01 g tolerance

1.230 g ±0.001 g tolerance

5.43g ±0.01 g tolerance

4.0000g ±0.0001 g tolerance

6.539g ±0.001 g tolerance

For the following, identify the most likely value for x.a. BHx b. CHx c. NHx d. CH2Clx

vekshin1

Given :

a. $BH_x$ b. $CH_x$ c. $NH_x$ d. $CH_2Cl_x$ .

To Find :

Find the most likely vale of x for each one .

Solution :

a . $BH_x$

Because boron have valency of 3 .

So , x = 3 .

b . $CH_x$

Valency of carbon is 4 .

x = 4 .

c . $NH_x$

Valency of nitrogen is 3 .

Therefore , x = 3 .

d . $CH_2Cl_x$

Now ,we know valency of carbon is 4 and hydrogen is 1 .

Also , two hydrogen are already there .

So , only 2 electrons left to share .

Since , chlorine have valency of 1 .

Therefore , only 2 electrons of chlorine can connect .

x = 2 .

Hence , this is the required solution .

Melting gold with other metals makes 10 karat gold. Which term best describes 10 karat gold

katrin2010 [14]

The 10 karat of gold formed by melting gold with other metals is described as homogeneous mixture.

A pure substance is a substance that is made up of only one kind of particle. This type of substance consist of only one element.

A heterogeneous substance is a type of substance that is made up two or more substances existing in different phases.

A homogeneous substance is a type of substance that is made up of two or more substances evenly mixed. This type of substance exist only in one phase.

Thus, the 10 karat of gold formed by melting gold with other metals is described as homogeneous mixture.

A sample of a compound is analyzed and found to contain 0.420 g nitrogen, 0.480g oxygen, 0.540 g carbon and 0.135 g hydrogen. Wh

RSB [31]

Answer:

C2H5NO

Explanation:

constituent elements N O C H

Mass composition 0.420 0.480 0.540 0.135

mole ratio 0.42/14 0.48/16 0.54/12 0.135/1

= 0.03 0.03 0.045 0.135

dividing by the smallest 0.03/0.03 0.03/0.03 0.045/0.03 0.135/0.03

ratio = 1 1 1.5 4.5

= 1 1 2 5

EMPERICAL FORMULA = C2H5NO

What is the balanced form of the following equation?. Br2 + S2O32– + H2O → Br1– + SO42– + H+.

zloy xaker [14]

For the equation to be balanced, the Atom's coefficient on the left side and the right side of the equation has to be equal

so, the answer would be :

Br2 + S2032- + 5H20 -- > BR2- + 2S02- + H+

Hope this helps
