Answer:

Yes

Explanation:

Chemical equation.

C₁₂H₂₂O₁₁ + 11H₂SO₄ → 12C + 11H₂SO₄ + 11H₂O

The sulfuric acid is used as a catalyst in the given reaction. Sucrose is break down into individual atoms carbon, hydrogen and oxygen.

Oxygen and hydrogen are combine to form water. The heat is released during the reaction and it is exothermic reaction. we can say that heat is given off because it is exothermic while in endothermic heat is taking by the substance.

Exothermic reaction:

The type of reactions in which energy is released are called exothermic reactions.

In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.

For example:

Chemical equation:

C + O₂ → CO₂

ΔH = -393 Kj/mol

it can be written as,

C + O₂ → CO₂ + 393 Kj/mol

Which of the following items is a salt? (1 point)

Tems11 [23]

Calcium carbonate is the salt among the given options.

Calcium carbonate ( CaCO3) can be regarded as which appears as white and odorless powder or as a colorless crystals it is insoluble in water.

The chemical formula is CaCO3. It can be used as an antacid as well as food colouring and a food firming agent and a fertilizer.

Calcium carbonate is calcium salt as well as carbonate salt with one-carbon compound

Salt can be regarded as substance which is produced by reaction between acid and base. It consists negative ion (anion) of that acid as well as positive ion (cation) of the base.

Sodium hydroxide is a base and not a salt

Carbonic acid is an acid and not a salt

Therefore, calcium carbonate is the only salt in the among the given options.

If a gas sample has a pressure of 30.7 kPa at 0.00*C, by how much does the temperature have to decrease to lower the pressure to

Scrat [10]

Answer:

252.68 K or -20.46 °C

Explanation:

According to Gay-Lussac's Law, "Pressure and Temperature at given volume are directly proportional to each other".

Mathematically,

P₁ / T₁ = P₂ / T₂ ---- (1)

Data Given:

P₁ = 30.7 kPa

T₁ = 0.00 °C = 273.15 K

P₂ = 28.4 kPa

T₂ = ???

Solving equation for T₂,

T₂ = P₂ T₁ / P₁

Putting values,

T₂ = 28.4 kPa × 273.15 K / 30.7 kPa

T₂ = 252.68 K or -20.46 °C

what is the molecular formula for a compound with the empirical formula: K2SO4 and a molecular mass of 696g

LekaFEV [45]

Answer:

K8S4O16 or K8(SO4)4 depending on if the SO4 is supposed to represent sulfate or not

Explanation:

Find the molar mass of K2SO4 first:

2K + S + 4O ≈ 174 g/mol

Divide the goal molar mass of 696 by the molar mass of the empirical formula:

696 / 174 = 4

This means you need to multiply everything in the empirical formula by 4:

K2SO4 --> K8S4O16 or K8(SO4)4 depending on if the SO4 is for sulfate or not

15) The different types of clouds are:

cumulus: Cumulus clouds are clouds which have flat bases and are often described as "puffy", "cotton-like" or "fluffy" in appearance. Their name derives from the Latin cumulo-, meaning heap or pile.

cirrus: Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands, that typically appear white or light grey. The name is derived from the Latin word cirrus, meaning 'ringlet' or 'curling lock of hair'. Such a cloud can form at any altitude between 5,000 and 13,700 m above sea level.

stratus: Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals.

nimbus: Nimbostratus clouds are dark, grey, featureless layers of cloud, thick enough to block out the Sun and produce persistent rain. Height of base: 2,000 - 10,000 ft. Shape: Bands or areas of individual cells. Latin: nimbus - rainy cloud; stratus - flattened or spread out. Precipitation: Continuous rain or snow likely.

18) Cirrus clouds

19) the ozone layer

20) Global winds are created by both the spin of

the Earth (Coriolis effect) and the differences

in temperature between the equator and

the polar areas. These winds are often

grouped together as trade winds, easterlies,

and westerlies.
