Answer:
1.0 V
Explanation:
Step 1: Given data
Resistance of certain conductor (R): 10 ΩCurrent's intensity (I): 100 mAPotential difference at the terminals of that conductor (V): ?Step 2: Convert "I" to Ampere
We will use the conversion factor 1 A = 1000 mA.
100 mA × 1 A/1000 mA = 0.100 A
Step 3: Calculate the potential difference
We will use Ohm's law.
V = I × R
V = 0.100 A × 10 Ω = 1.0 V

c) [tex]2Al+3H_2SO_4\rightarrow Al_2(SO_4)_3+3H_2[/tex]
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.
The balanced chemical equations are :
[tex]H_3PO_4+3NaOH\rightarrow Na_3PO_4+3H_2O[/tex]
[tex]PCl_3+3H_2O\rightarrow P(OH)_3+3HCl[/tex]
[tex]2Al+3H_2SO_4\rightarrow Al_2(SO_4)_3+3H_2[/tex]

how does the law of conservation of mass applies to all chemical reactions?
Answer:
the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
Explanation:
The law of conservation is Matter cannot be created or destroyed in chemical reactions so it means exactly that
Zinc sulfide and oxygen gas react to form zinc oxide and sulfur dioxide. Determine the amount (g) of SO2 that should be produced in a reaction between 32.5 g of ZnS and 23.3 g of oxygen gas. What is the mass of the xs reactant?
Answer:
7.30g O₂ are in excess and 21.3g of SO₂ should be produced.
Explanation:
The reaction of Zinc sulfide (ZnS) with oxygen (O₂) produce ZnO and SO₂ as follows:
2ZnS + 3O₂ → 2ZnO + 2SO₂
Using this reaction we can find the amount of SO₂ produced converting the ZnS and O₂ to moles and finding limiting and excess reactant as follows:
Moles ZnS -Molar mass: 97.47g/mol-:
32.5g * (1mol / 97.47g) = 0.333 moles ZnS
Moles O₂ -Molar mass: 32g/mol-:
23.3g O₂ * (1mol / 32g) = 0.728 moles O₂
For a complete reaction of the 0.333 moles of ZnS are required:
0.333 moles ZnS * (3mol O₂ / 2mol ZnS) = 0.500 moles O₂.
As there are 0.728 moles of O₂, limiting reactant is ZnS and excess reactant is O₂.
The moles and mass of O₂ in excess are:
0.728mol - 0.500mol = 0.228moles O₂ * (32g / mol) = 7.30g O₂ are in excess
The produced mass of SO₂ -Obtained from the moles of ZnS- is:
0.333 moles of ZnS * (2mol SO₂ / 2mol ZnS) = 0.333 moles SO₂
0.333 moles SO₂ * (64.066g / mol) =
21.3g of SO₂ should be producedGive the number of protons, electrons and neutrons in one atom of Carbon.
Answer:
6 protons, 6 neutrons, and 6 electrons.

What are two things in nature that solar energy powers?
Answer: light and heat
Explanation:Our sun is the source of all life on Earth, and solar energy is useful to us in many different ways. The sun creates two main types of energy - light and heat - that we can harness for many activities ranging from photosynthesis in plants to creating electricity with photovoltaic (PV) cells to heating water and food.
Which type of data relies on the senses or things you can't measure
Answer:
Nominal data
Explanation:
This is a type of data in which its set of values don't have a nominal arrangement.
For example, the color of a football jersey can be deemed as a nominal data type as we can’t distinguish one color from others. Like It is impossible to declare that ‘Pink' is greater than ‘Yellow'.

Atoms of two distinct elements are bound together by covalent bonds to form binary covalent compounds. They typically contain nonmetal elements, such as laughing gas NO, a gas that causes acid rain SO₂, etc. Binary covalent compounds are those that consist of just two components.
The definition of a covalent compound is one in which the atoms are joined by a covalent connection. Compounds with just two elements are referred to as binary covalent compounds.
The name of the given compounds are:
CO₂: Carbon Dioxide
CS₂: Cardon Disulfide

Which of the following halogens has the largest atomic radius?
a. Chlorine
b. lodine
c. Bromine
d. Fluorine
Answer:
[tex]\boxed {\boxed {\sf B. \ Iodine }}[/tex]
Explanation:
Atomic radius is the measurement from the nucleus to the outer edge of the electron cloud.
As you go down a group (vertically) the atomic radius increases because more electron shells are added. As you go across a period horizontally, the atomic radius decreases.
If we look at the halogens group (17), we see they follow this order from top to bottom:
F - Fluorine
Cl - Chlorine
Br - Bromine
I - Iodine
Since it increases down the group, iodine must have the largest atomic radius.
