What is the electron configuration for boron (B)?

Answer:

DICLORURO DE ZINC

Explanation:

La ecuación es:

Zn (s) + 2HCl (aq)  →  ZnCl₂ (aq) +H₂ (g)

El zinc reacciona en una reacción redox con el acido clorhídrico para formar una sal y liberar el hidrogeno gaseoso.

Se trata de una reacción redox porque el hidrógeno se reduce (disminuye el numero de oxidación, de -1 a 0, en su estado fundamental), mientras que el Zn se oxida (el numero de oxidación aumenta de 0 a +2).

Como la sal se forma con dos atomos de cloro, se denomina dicloruro por lo que el nombre correcto de la sal en nomenclatura sistemática es:

- DICLORURO DE ZINC

Answer:

Velocity

Explanation:

Velocity is a vector quantity that mentions the direction of the object(north, south, etc..) speed is not a vector quantity.

I think this is the answer, I hope this helps!

Answer:kinetic

Explanation:

Thank

Answer:

B.

Explanation:

The block has potential energy.

ITS [tex]C_{4}H_{10}[/tex] AND [tex]C_{5}H_{12}[/tex]

Where n is the number of CARBONS

A)

By using the General Formula of Alkanes having 4 carbon atoms is

                        [tex]C_{4}H_{2x4+2}[/tex]

                        [tex]C_{4}H_{10}[/tex]

C)

By using the General Formula of Alkanes having 5 carbon atoms is

                         [tex]C_{5}H_{2x5+2}[/tex]

                         [tex]C_{5}H_{12}[/tex]

IF YOU USE THE SAME FORMULA FOR THE OTHER TWO OPTIONS THE OUTCOME WILL NOT BE AS SAME AS GIVEN IN THE QUESTION SO THOSE TWO ARE CAN NOT BE OUR ANSWER

Explanation:

Because if the family has the same disease and DNA then the cure will be compatible.

Answer:

decrease

Explanation:

Answer:

Climate change leads to a loss of species

With these changes, species have to adapt to new climate patterns (variations in rainfall; longer, warmer summers etc). ... The consequences include habitat loss; shifts in climatic conditions and in habitats that surpass migrational capabilities; altered competitive relationships.

Explanation:

Thank you

The question is asking you to compare each elements electrons, specifically valence since it mentioned their placement on the table.

Similarly: they both are only one electron away from stability (a full octet)

Difference: Sodium will want to loose the one electron, and Chlorine will take it.

Answer:

radiation and reflection

Explanation:

Energy is send from space to earth by radiation and reflection. The most predominant way in which heat is transferred from earth to space is by radiation.

Answer:

radiation and reflection

Answer:

Fal down to the flour

Explanation:

Because of gravity their is weight that weight keeps us down to earth everything has weight even a leaf not only weight but the atmosphere is like a wall that keeps us safe from all the stuff in space.

The initial temperature of the metal = 35 °C

Heat can be formulated :

Q = m . c . ΔT

Q = heat, J

c = specific heat, J/g C

ΔT = temperature, °C

m = 20 g

c = 5 J/(g°C)

Q = 500 J

T₁ = 40 C

the initial temperature :

[tex]\tt \Delta t(T_2-T_1)=\dfrac{Q}{m.c}\\\\40-T_1=\dfrac{500}{20.5}\\\\40-T_1=5\\\\T_1=35^oC[/tex]

Answer:

Single-Replacement Reaction

General Formulas and Concepts:

Types of Reactions

Explanation:

Step 1: Define reaction

CaCl₂ + F₂ → CaF₂ + Cl₂

Step 2: Identify backplate

Single-Replacement Reactions: A + BC → AB + C

BC = CaCl₂

A = F₂

AB = CaF₂

C = Cl₂

Answer:

Explanation:

Total moles = 300 + 500 = 800 moles

mole fraction of carbon dioxide = 300 / 800 = 3 / 8

water = 500 / 800 = 5 / 8

Total pressure = 21 atm

partial pressure of water = total pressure x mole fraction of water

= 21 x 5 / 8

= 13.125 atm

Answer:

0.025 moles of NO₂  will produced

Explanation:

Given data:

Moles of NO₂ formed = ?

Volume of HNO₃ = 25.0 mL

Molarity of HNO₃ = 2 M

Solution:

Chemical equation:

Cu + 4HNO₃   →        Cu(NO₃)₂ + 2NO₂ + 2H₂O

Number of moles of HNO₃:

Molarity = number of moles /  volume in L

2M = number of moles / 0.025 L

Number of moles = 2 M × 0.025 L

Number of moles = 0.05 mol

Now we will compare the moles of HNO₃  with NO₂  from balance chemical equation.

                                  HNO₃            :          NO₂

                                      4                :            2

                                 0.05               :         2/4×0.05 =0.025

0.025 moles of NO₂  will produced.

Answer:

A digital camera. You can zoom and all that stuff and see individual pixels when  close up. Also none of the other options would make sense.

Explanation:

Answer: A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound.  here's an example Acetic acid formula CH3COOH. the compound factors it is The electron affinity or the ionising potential. here are elements of making compounds CaCo3 is a Calcium and a carbonate CaCl2 is a calcium and a chlorine

C3H60 is three Calcium’s and 60 hydrogens

HCL is one hydrogen and a chlorine

Ca(OH)2 is one calcium and two hydroxides (OH-).
