canals and irrigation is the answer

Answer:

You will need to have a red flower in the top left, a pink flower in the top right and bottom left, and a white flower in the bottom right.

Explanation:

This flower appears to express color through codominance, which means that both genes express themselves. "R" is the dominant gene for red, and "r" is the recessive gene for white. When a flower has RR genotype, the phenotype will be a red flower. When a flower has an Rr genotype, the red and white genes will both be expressed and the phenotype will be pink. When a flower has an rr genotype, it lacks the red gene and will therefore be only white.

Answer:

sulfite ion SO32

Explanation:

A molecular ion is a covalently bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero.

To balance a chemical equation, both sides should have equal mass, or in other words both sides should have same number of atoms as to follow the conservation of mass rule.

P + O₂ = P₄O₆

LHS:

Number of Phosphorus atoms = 1 atom

Number of Oxygen atoms = 2 atoms

RHS:

Number of Phosphorous atoms = 4 atoms

Number of Oxygen atoms = 6 atoms

Also since P₄O₆ has the most number of atoms we will make the LHS equalize to P₄O₆.

Difference between Phosphorous atoms in LHS to RHS = 3

Since phosphorous is a monatomic we need 3 phosphorous atoms extra

Difference between Oxygen atoms is LHS to RHS = 4

But Oxygen is diatomic, so we need 4/2 = 2 Oxygen molecules

Now lets see if it is balanced

P + 3P + O₂ + 2O₂ -------> P₄O₆

               4P + 3O₂ ------>  P₄O₆

LHS:

Phosphorous atoms = 4 atoms

Oxygen atoms = 3 × 2 = 6 atoms

RHS:

Phosphorous atoms = 4 atoms

Oxygen atoms = 6 atoms

LHS = RHS

Therefore the balanced equation is 4P + 3O₂ =  P₄O₆

Answer: 44.706g Al2O3

Explanation:

4A1 + 302 → 2Al2O3

3×(16×2) 2{(27×2)+(16×3)}

= 96 = 204

So

To produce 204g of Al2O3,We need . 96g of O2

To produce 1g of Al2O3,We need

. (96÷204)= 0.47g of O2

To produce 95g of Al2O3,We need

. (0.47×95)= 44.706g of O2

.

So, 44.706 grams of oxygen (O2)

are needed to produce 95 grams of

aluminum oxide (Al2O3).

The mass of NaHCO₃ needed to produce 2.659 moles of CO₂ is 446.712 g

We'll begin by writing the balanced equation for the reaction. This can be obtained as follow:

2NaHCO₃ —> Na₂CO₃ + CO₂ + H₂O

Molar mass of NaHCO₃ = 23 + 1 + 12 + (16×3)

= 84 g/mol

Mass of NaHCO₃ from the balanced equation = 2 × 84 = 168 g

From the balanced equation above,

168 g of NaHCO₃ decomposed to produce 1 mole of CO₂.

With the above information, we can obtain the mass of NaHCO₃ needed to produce 2.659 moles of CO₂. This can be obtained as follow:

From the balanced equation above,

168 g of NaHCO₃ decomposed to produce 1 mole of CO₂.

Therefore,

Xg of NaHCO₃ will decompose to produce 2.659 moles of CO₂ i.e

Xg of NaHCO₃ = 168 × 2.659

Xg of NaHCO₃ = 446.712 g

Thus, 446.712 g of NaHCO₃ is needed to produce 2.659 moles of CO₂.

Answer:

1.3142 mol CoCl2

Explanation:

Well, to answer this we need to find out how many grams are in a single mole of CoCl2. Two find that we need to get the molar mass of CoCl2

Co = 28.0101 g Co per mole

Cl = 35.453 * g Cl per mole

28.0101 + 2 * 35.453 = 98.9161 g CoCl2 per mole

Now, we divide:

130/98.9161 = 1.3142 mol CoCl2

There are 1.31 moles in 130grams of cobalt chloride (CoCl2). Details about how to convert mass to moles can be found below.

The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass.

According to this question, there are 130g of CoCl2.

molar mass of CoCl2 = 28 + 35.5(2) = 99g/mol

moles = 130g ÷ 99g/mol

moles = 1.31 moles

Therefore, there are 1.31 moles in 130grams of cobalt chloride (CoCl2).

Answer:

Atomic size decreases on going along a period from left to right because the electron enters into the same shell, therefore, attraction between nucleus and outermost electron increases and thus atomic size decreases. Valency first increases from 1 to 4 and then decreases from 4 to GO along a period from left to right.
