What is the name and formula of an ionic compound containing the element with the
atomic number of 5 bonded to Carbonate? *
Boron Carbonide; B2(CO3)3
Boron Carbonate; B,CO,
Boron Carbide; B,CO,
Boron Carbonate; B2(CO3)3
Answer:
Boron Carbonate; B₂(CO₃)₃
Explanation:
For names, carbonide does not exist; that rules out the first option. Carbide refers to just a carbon atom, not carbon and oxygen as in the polyatomic ion carbonate. That rids us of the third option. We are left with boron carbonate with the formula BCO or boron carbonate with the formula B₂(CO₃)₃.
Recall the carbonate polyatomic ion's formula: CO₃²⁻
Thus BCO cannot be the formula.
Option 4 is your answer, Boron Carbonate; B₂(CO₃)₃.
To further check your answer, observe the oxidation states of boron and the polyatomic ion carbonate. Boron can exist in oxidation states of either 2+ or 3+, and carbonate is only 2-; in this formula, boron will exhibit a 3+ state to balance out with carbonate.
2x3+ = 6+; 3x2- = 6-
6+ + 6- = 0; balanced

Calcium carbonate (limestone) decomposes when heated.
Caco, + CaO + CO2
b) Calculate the volume of carbon dioxide produced if 10 grames were decomposed.
Explanation:
Equation -
CaCO₃ → CaO + CO₂
molecular masses of -
CaCO₃ = 40+12+16×3 = 100 g/mol
CaO = 40+16 = 56 g/mol
CO₂ = 12+16×2 = 44 g/mol
Now,
If 100 g of CaCO₃ is decomposed then it produces 56 g of CaO and 44g of CO₂
Then,
If 1 g of CaCO₃ is decomposed then it produces 56/100g of CaO and 44/100g of CO₂
Now,
Here in question, 10g of CaCO₃ is decomposed
It means, It produces
56/100 × 10 = 56/10 = 5.6 g of CaO and
44/100 × 10 = 44/10 = 4.4 g of CO₂
Now,
we get that 10 g of CaCO₃ on burning produces 4.4 g of CO₂
we need to calculate volume of 4.4 g of CO₂
mole = mass/Gram molecular massThen,
mole = 4.4/44 = 0.1
Now,
volume = mole × 22.4 (in Litres)
= 0.1 × 22.4 = 2.24 L
Hence,
2.24 L of CO₂ will be produced when 10g of CaCO₃ decomposed.
How does a longshore current change the beach
Answer:
As this sheet of water moves on and off the beach, it can “capture” and transport beach sediment back out to sea. This process, known as “longshore drift,” can cause significant beach erosion.
Carbon dioxide is formed by the given formula.

A
a compound of two elements, carbon and oxygen.
B
a mixture of two compounds, carbon and oxygen.
C
a compound of two atoms, carbon and oxygen.
D
an element of two atoms, carbon and oxygen.
Answer:
A
Explanation:
An object has a mass of 441 g and a volume
of 10 cm3. What is the density of the object
in g/cm3?
The density is the ratio of the mass to the volume. The density of the object is 44.1 g/cm³.
What is density?Density (ρ) is the quantitative measurement of the substance having grams of mass that are dissolved per cubic meter of the solution. The density is calculated as:
ρ = M ÷ V
Given,
Mass of the object = 441 gm
The volume of the object = 10 cubic meter
Density is calculated as:
ρ = 441 ÷ 10
= 44.1 g/cm³
Therefore, 44.1 g/cm³ is the density of the object.

If the temperature of a substance increases will the particles of that substance be moving faster or slower or at the same speed as they were before the temperature changed
Answer:
If the temperature increases, temperature reflects the speed of the molecules, so if the molecules are at a higher temperature, they are faster and they start to break bonds and new things react.

Which of these describes a challenge that the engineer of a high-altitude
airplane would need to consider?
A. More fuel is used at higher altitudes.
B. The airplane may succumb to the power of gravity as lift
decreases at higher altitudes.
C. The airplane may need a heat shield for protection from sonic
booms.
O D. The airplane will create more drag at higher altitudes than lower
altitudes.
Answer:
I think its (B)
Explanation:
as when the air thins out at higher elevations, your lift decreases so at some point, the plane cant produce enough lift to overcome gravity.

why do the Noble gases have the highest ionization energies across a period?
Answer:
ionization energy decreases from top to bottom in groups, and increases from left to right across a period. So technically, the noble games have the largest ionization energy.

We can verify the properties as follows;
1) Sour taste - Put some soda on your tongue
2) Corrode metals - Put a little soda on a clean metal surface
3) Effect on Litmus paper - Dip a blue litmus paper in soda
4) Electrolysis - Add two electrodes to soda and connect a battery.
Does Soda show acidic properties?Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.
When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:
CO₂ + H₂O ⇌ H₂CO₃

What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
