Around 2.0 L of ethylene glycol needs to be added to the car radiator
Explanation:
The depression in freezing point ΔTf of a solution is directly proportional to its molality (m), i.e.
From the given information:
= freezing pt of solution = -10.0 C
= freezing pt of pure solvent = 0 C
Kf = freezing pt depression constant = 1.86 C/m
i = 1 for ethylene glycol antifreeze
Volume of water = 6.50 L = 6500 ml
Density of water = 1.00 g/ml
Therefore mass of water =
Molar mass of ethylene glycol = 62 g/mol
Mass of ethylene glycol needed =
Density of ethylene = 1.11 g/ml
Therefore, volume needed =
m = 8.60 = moles solute / 6.50 Kg
moles solute = 55.9
mass solute = 55.9 x 62.068 g/mol=3470 g
V = 3479/ 1.11 =3126 mL= 3.13 L
delta T = 8.60 x 0.512 =4.40
boling point = 104.4 °C

The chemical equation 2 C₂H₂ +5 O₂ + 4 CO₂ + 2 H₂O is the equation which represents the combustion of a hydrocarbon.
What is a chemical equation?
Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Answer:
20 mL
Explanation:
We can determine the required volume of the concentrated (17.5 M) H₂SO₄ solution by using the C₁V₁=C₂V₂ formula:
- 17.5 M * V₁ = 14.00 M* 100 mL
- V₁ = 80 mL
As out of the 100 mL of the final solution, 80 mL are from the concentrated H₂SO₄ solution, the remaining 20 mL are of water (H₂O).

The concave lens is a lens which has an inward curve in the middle, that is, the edges of the curve are thicker than the center of the lens, because of this, any light that enter the lens will spread out [diverge]. An image will look smaller and upright when viewed by a concave lens. Image formed by concave lens are usually VIRTUAL.
A concave lens will produce a real image ONLY if the object is located beyond the focal point of the lens.
A convex lens is a converging lens, this is because, the center of the lens is thicker than its edges. Any ray of light that passes through the lens will converge at the middle of the lens at point called principal focus. A convex lens produce a VIRTUAL image when the object is placed infront of the focal point. The virtual image formed is always magnified and upright.
The image formed by any lens like concave and convex may be real or virtual.
How many types of lens are present?
Mainly two types of lens are present and that are concave lens also known as divergent lens and convex lens, also known as convergent lens.
- Any light passing through the lens will disperse [diverge]. When viewed through a concave lens, an image seems smaller and more upright. Concave lenses frequently produce VIRTUAL images and concave lens will produce a real image only if the object is located beyond the focal point of the lens.
- Any beam of light passing through the lens will converge in the lens's center, known as the main focus. When an object is placed in front of the focal point, a convex lens produces a VIRTUAL image. The resulting virtual picture is constantly amplified and oriented vertically.
Hence image formed by a lens may be real or virtual.
