For this problem, you first find the net resistance of the circuit which can be done by adding up the resistors since this circuit is a series. 10Ω+5Ω+6Ω=21Ω

Since we are given the current of 6A, we can use Ohm’s Law of V=IR.

V=6A*21Ω

V=126 volts

I need help like extremely bad
Anna007 [38]

Answer:

First start with the ones we know

Explanation:

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3.dna- is all the chromosomes (genetic material)

A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell

a pair - so must be bigger than one chromosome

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3. homologus pair

4.dna- is all the chromosomes (genetic material)

now 5.

A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA. DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes.

1. small - gene

2.chromosome - chromosomes contain genes so they must be bigger

3. homologus pair

4.dna- is all the chromosomes (genetic material)

5. genome - all the DNA

Identify two acids and two bases that you use or come into contact with in an average week. Identify uses for each substance.
skelet666 [1.2K]

Explanation:

Two acids we come into contact with in an average week

  1. Vinegar is an 10% solution of acetic acid (CH_3COOH)in water. Used in salad dressing and while cooking food. It has a sour taste.
  2. Citric acid present in fruits and vegetables like : lemons, orange, tomatoes etc. It is a weak organic acid with sour taste.

Two bases we come into contact with in an average week.  

  1. Baking soda (NaHCO_3) is used in baking food like: cakes, cookies, breads. Baking soda is one of the ingredient while baking breads and cakes.
  2. Caustic soda (NaOH) is used for preparation of detergents, papers , soaps etc. We use soaps and detergents for washing.

What is the limiting reactant if 12 moles of p4 react with 15 moles of o2?.
brilliants [131]

Answer:

see explanation

Explanation:

To determine limiting reactant divide mole quantities of reactants by the respective coefficient in the balanced equation. The smaller value is the limiting reactant.

    P₄      +     5O₂       => 2P₂O₅

12/1 = 12      15/5 = 3

O₂ is the limiting reactant. P₄ will be in excess when rxn stops.

Assuming the reaction is first order in sucrose, determine the mass of sucrose that is hydrolyzed when 2.75 L of a 0.130 M sucro
Advocard [28]

Answer:125.84g

Explanation:Sucrose is dissacharides an organic compound in the class of carbonhydrate with the chemical formula C11H22O11.molar concentration is given by number of moles/Volume,this implies that moles=molar concentration ×Volume=0.130M×2.75L=0.3575moles.

Furthermore,number of moles=Mass of Sucrose/molecular Mass of Sucrose.

From it's formular C11H22O11, molecular Mass is the addition of the mass number which is 12 for C,2 for H and 16 for oxygen,O.so molecular Mass of Sucrose is (12×11)+(2×22)+(16×11)=352.

So mass =moles ×molecular mass=0.3575moles×352g/moles=125.84g
