Question 3 options:
4.5 cups of Sugar
3.5 cups of Sugar
3.5 cups of lemon juice
4.5 cups of lemon juice
Answer:
1.) 12 tablespoons of sugar and 3 cups of water (48 tablespoons)
2.) Amount of lemon juice, sugar and water required will be = 0.375 cups, 0.75 cups and 3 cups.
Step-by-step explanation:
Malanie is making lemonade and finds a recipe that requires lemon juice, sugar and water in the ratio of 1 : 2 : 8.
She juices 2 lemons to obtain 6 tablespoons of lemon juice.
∵ 16 tablespoons = 1 cup
∴ 1 tablespoon = cup
∴ 6 tablespoon = cup = 0.375 cups
Since ratio between lemon and sugar is 1 : 2
So amount of sugar required = 0.375×2 = 0.75 cups
Ratio between lemon and water is 1 : 8
So amount of water required = 0.375×8 = 3 cups
Therefore, amount of lemon juice, sugar and water required = 0.375 cups, 0.75 cups sugar and 3 cups respectively.
Explanation:
Answer:
18 cups.

Predict the products of the following reaction:
RbNO2 +BaCO3->
Answer:
2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2
Explanation:
The balanced reaction equation is shown below;
2RbNO2 + BaCO3 → Rb2CO3 + Ba(NO2)2
This reaction is possible because the reduction potential of Rb is -2.98V while that of Ba is –2.92 V. Hence Rb can displace Ba from its salt solution.
The equation is balanced since the number of atoms of each element on the left and right hand sides of the reaction equation are equal.
The products for the reaction of Rubidium nitrite and Barium carbonate has been Barium nitrite and Rubidium carbonate.

Evaluate each statement and determine which statement is not a determining factor in the formation of intrusive igneous rocks? Group of answer choices Magma cools very fast beneath the Earth's surface None of these Slow cooling allows large crystals to grow The Earth's interior has very high temperatures
Answer: The statement that is not a determining factor in formation of intrusive igneous rocks is 'None of the above' and Magma cools very fast beneath the Earth's surface.
Explanation:
Rocks are naturally occurring solid materials that are made up of different types of minerals which affects it's texture and colours. The three main types of rocks are:
--> sedimentary rocks,
--> metamorphic rocks and
--> igneous rocks.
Igneous rocks are formed from the crystallization and solidification of hot molten rocks which originates from deep within the earth. Depending on where the molten rock solidifies, the igneous rock is divided into two, namely:
--> intrusive igneous rock and
--> extrusive igneous rock.
The INTRUSIVE IGNEOUS rocks are formed within or deep beneath the earth surface when the hot magma SLOWLY cools over millions of years until it solidifies. The slow cooling allows large crystals to grow.
Therefore the statements (None of the above and Magma cools very fast beneath the Earth's surface) are not a determining factor.
500 mL solution of calcium chloride with a concentration of 0.75 mol/L. The mass of solute needed to make this solution is ___ ___ ___ ___ g.
Answer:
41.63g
Explanation:
Given parameters:
Volume of CaCl₂ = 500mL = 0.5L
Concentration = 0.75mol/L
Unknown:
Mass of the solute needed = ?
Solution:
The mass of the solute can be derived using the expression below;
Mass = number of moles x molar mass
But,
Number of moles = Concentration x Volume
So;
Mass = Concentration x Volume x molar mas
Molar mass of CaCl₂ = 40 + 2(35.5) = 111g/mol
Mass = 0.75 x 0.5 x 111 = 41.63g

C: When an acid reacts with a carbonate, carbon dioxide is given off.
D: When the acidity of a solution increases, the pH increases.
Answer:
D: When the acidity of a solution increases, the pH increases.
Explanation:
It is totally wrong to assert that when the acidity of a solution increases, the pH of the solution will increase
The right answer is that when the acidity of a solution increases, the pH value decreases.
The pH scale records the level of acidity and basicity of a substance. It runs from 1 to 14From 7 to 14 signifies increasing basicity As the acidity of a substance increases, the pH value reduces. For acids 1 is the highest acidity levels.Which two characteristics are associated with metals

What is the percent of Li in
Li3N?
(Li = 6.94 amu, N = 14.01 amu)
Answer:
The percentage by mass of lithium in one mole of Li₃N is approximately 59.78%
Explanation:
The given compound is Li₃N
The atomic mass of lithium, Li = 6.94 amu
The atomic mass of nitrogen, N = 14.01 amu
Therefore by definition, we have;
The mass of one mole of lithium, Li = 6.94 g
The mass of one mole of nitrogen, N = 14.01 g
One molecule of Li₃N contains 3 atoms of lithium, Li and 1 atom of nitrogen, N
The mass of one mole of Li₃N = The molar mass of Li₃N = 3 × The mass of one mole of lithium + The mass of one mole of nitrogen
∴ The mass of one mole of Li₃N = 3 × 6.94 g + 14.01 g = 34.83 g
The percentage by mass of lithium, Li, in one mole of Li₃N = 3×6.94/(34.83) × 100 ≈ 59.78%
The percentage by mass of lithium in one mole of Li₃N ≈ 59.78%.

What type of ion would radium (88Ra) become when forming an ionic compound, and what would the oxidation number be?
A) a cation with a +2 charge
B) a cation with a -2 charge
C) an anion with a +1 charge
D) an anion with a -1 charge
Answer:
The correct option is A
Explanation:
Radium is an atom with the atomic number of 88. It is a metal found in group 2 of the periodic table; meaning that it has two valence electrons in it's outermost shell. As a metal that wants to form an ionic compound, radium would have to lose these two valence electrons to become a divalent positively charged cation (Ra²⁺). Thus, the correct option is A

Rate of consumption of N₂ = - 1.25 x 10⁻⁴
Further explanationThe reaction rate (v) shows the change in the concentration per unit time.
[tex]\tt rate=\dfrac{concentration(M)}{time(s)}[/tex]
The rate reaction for Haber Bosch :
N₂(g)+3H₂(g)⇒2NH₃(g)
From equation, mol ratio N₂ : NH₃ = 1 : 2, so
the rate of formation of ammonia = 2 x the rate of consumption of nitrogen.
Given
the rate of formation of ammonia gas : 2.5x10⁻⁴ M/s
the rate of consumption of nitrogen :
[tex]\tt \dfrac{2.5\times 10^{-4}}{2}=1.25\times 10^{-4}[/tex]
The sign negative for consumption : -1.25 x 10⁻⁴ M/s
or we can use another way:
Rate of formation of NH₃ = reaction rate x coefficient of NH₃
2.5 x 10⁻⁴ = reaction rate x 2
reaction rate = 1.25 x 10⁻⁴
Rate of consumption of N₂ = reaction rate x coefficient of N₂
Rate of consumption of N₂ = 1.25 x 10⁻⁴ x 1
Rate of consumption of N₂ = 1.25 x 10⁻⁴
