A student has a solid block of steel and a solid plastic block of the same size.

Chemistry
1 answer:
Colt1911 [192]3 years ago
4 0

The answer is the mass of the steel block is greater than the mass of the plastic block.

<u>Explanation</u>:

  • Steel has more thickness than plastic and wood. In this way, its mass will be more noteworthy and thus it will have a more noteworthy estimation of inertia, as inactivity of a body is estimated by the mass of the body. The mass of the steel is more noteworthy than the mass of the plastic.
  • Here the thickness of steel is more than plastic and wood. On the off chance that an article has more thickness than the other item, their masses would be more prominent because mass is corresponding to thickness.

First we need to find the limiting reactant. This is the reactant that is theoretically consumed completely first. Theoretical yield is how much product is produced given the limiting reactant is consumed and the percent yield is the fraction of the actual products produced and the theoretical products produced. 

The limiting reactant is <span>Pb(<span>C2</span><span>H3</span><span>O2</span><span>)2. 
The theoretical yield is </span></span>1.2373008g and you should get the Percent yield which is Actual yield/theoretical yield. <span />

Of the following, which can be used to identify an element present in a sample?
Anuta_ua [19.1K]

Answer:

idk but i tryed

Explanation:

The simplest way to use the periodic table to identify an element is by looking for the element’s name or elemental symbol. The periodic table can be used to identify an element by looking for the element’s atomic number. The atomic number of an element is the number of protons found within the atoms of that element.

A binary compound created by reaction of nitrogen and an unknown element E contains 30.46% N and 69.54% E by mass. If the formul
aleksklad [387]

Answer:

15.95

Explanation:

This question is a modification of the calculation of  the empirical formula of a compound given its percent composition and atomic weights of the elements in the compound.

Here we are given the formula and the percent composition, so we know that there are 4 atoms of E per 2 atoms of N so lets solve using the information given.

In 100 grams of the binary compound we have

30.46 g N

69.54 g E

The number of moles is the mass divided by atomic weight:

mol N = 30.46 g / A.W N = 30.46 g / 14.00 g/mol = 2.18 mol N

mol E = 65.54 g / A.W E

Thus,

4 mol E/ 2 mol N = ( 69.54 g/ A.W E ) / 2.18

2  A.E = 65.54 g / 2.18  ⇒ A.W E = 69.54 g / ( 2 x 2.18 ) = 15.94 g

So the A.W is 15.94 g/mol which is close  the atomic weight of O.
