Given the following equation...
Fe + H2SO4 → Fe2(SO4)3 + H2
What is the charge (oxidation number) of Fe in Fe2(SO4)3 in 334 g of Fe2(SO4)3 ? (use atomic masses rounded to the nearest whole number.)

Answers

Answer:

The charge is +3

Explanation:

In Fe₂(SO₄)₃ the global charge is 0.

As we know, the sulfate ion, SO₄, has a charge of -2, as there are 3 SO₄ ions in the molecule, the global charge is -2*3 = -6. To solve for the charge of Fe we can use:

2Fe - 6 = 0

2Fe = +6

Fe = +3

The charge of the Fe of Fe₂(SO₄)₃ is +3

Answer:

+3

what is the mass of 1.46 mole of zinc?

Answers

Answer:Zinc grams to moles

Molar mass of Zinc(Zn) = 65.38 g/mol. This means 1 mol of Zn is 65.38g . To find the number of moles of Zn, we divide the given amount of Zn by the molar mass of Zn. Hence, 1.34 g of Zn contains 0.020 moles of Zinc

Explanation:

1 mole is equal to 6.023 × 10 ²³ molecules. The mass of 1.46 mole of zinc is 1.34 grams.

What do you mean by mole ?

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

The mole concept can be used to convert between mass and number of particles.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

Molar mass of Zinc(Zn) = 65.38 g/mol.

This means 1 mol of Zn = 65.38g .

To calculate the number of moles of Zn, we divide the given amount of Zn by the molar mass of Zn.

Hence, 1.34 g of Zn contains 0.020 moles of Zinc.

Many plants in rainforests have leaf tips that come to a point, so precipitation drains off the leaf. This helps to keep the plant safe from harmful germs. Based on this info, what resource is prevalent in a rainforest?

Answers

Answer:

rainfall/water

Explanation:

The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.

Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.

water, H20
CLEAR ALL

Answers

Answer:

water, H20

Explanation:

From the given choices, only water has two unshared or lone pairs of electrons in its central atom.

The formula of water is:

              H₂O

H is hydrogen with 1 electron

O is oxygen with 8 electrons and 6 valence electrons

To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.

The remaining 4 gives the two lone pairs.

Answers

Answer:

a weighing balance, a measuring cylinder, a spatula, a beaker/flask, and a stirrer

Explanation:

The lab apparatus that would be needed to prepare a solution of sodium chloride would be a weighing balance, a measuring cylinder, a spatula, a beaker/flask, and a stirrer.

The weighing balance would be used to weigh out the required amount of sodium chloride. The beaker or flask would be placed on the weighing balance and its weight zeroed. The spatula would then be sued to take out the sodium chloride from its container into the beaker till the required amount is reached. The measuring cylinder would then be used to measure out the required volume of water which would be added to the salt in the beaker. The stirrer would then be used to stir the mixture in order for the salt to dissolve.

You bought your pig and it weighed 82 pounds. By fair your goal weight is 267 pounds. Your pig will gain 1 pound for every 3 pounds of feed. How much feed will you need to get your pig to it's goal weight? (show your work) (5) Feed costs $21.37 per 50 pound bag. How much will your feed cost be, to get your pig to it's goal weight? (5) MUST SHOW ALL WORK.

Answers

Number of feed = 555 pounds

Feed cost = $237.21

Further explanation

The main composition of algebraic expressions are:  

• 1. phrases/terms  

• 2. variable  

• 3. constants  

• 4. arithmetic operations  

• 5. coefficients  

• 6. exponent  

Initial weight = 82 pounds

Goal weight = 267 pounds

The difference in weight that must be achieved :

[tex]\tt 267-82=185~pounds[/tex]

The pig will gain 1 pound for every 3 pounds of feed⇒ 1 pound weight=3 pounds of feed

The amount of feed must be given:

[tex]\tt 185~pounds~weight\times 3~pounds~feed=555~pounds~of~feed[/tex]

Feed costs $21.37 per 50 pound bag, so for 555 pounds :

[tex]\tt (555~pounds\div 50)\times \$21.37=\$237.21[/tex]

A radioactive nucleus can change from one element to another. How does this happen?

Answers

Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. This process changes the atom to a different element or a different isotope

A radioactive decay is occurring by the emission of charged particles such alpha or beta to form a new stable atom with changes mass number and atomic number.

What is radioactive decay?

Heavy unstable radioactive elements undergo nuclear decay by which they form a stable isotope or new atom with changed atomic number. There are two types of nuclear decays mainly. They are alpha decay and beta decay.

During alpha decay isotopes with higher mass number undergo alpha emission and forming a new species with mass number reduced by 4 units and atomic number reduced by 2 units.

In the case of beta- decay, electrons are emitted from the atom and then forming a new atom with atomic number increased by one unit. For an electron capture process, an electron is captured to the atom forming an element with atomic number reduced by one.
