Answer:

^{32}_{14}Si\rightarrow ^{32}_{15}P+e^-+\bar{v}_e

Explanation:

Beta decay conserves the lepton number. In \beta^- decay, the atomic number of the element increases which is accompanied by the release of  an electron antineutrino, e^-+\bar{v}_e.

For example:-

^A_ZX\rightarrow ^A_{Z+1}X+e^-+\bar{v}_e

The \beta^- decay of silicon-32 is shown below as:-

^{32}_{14}Si\rightarrow ^{32}_{15}P+e^-+\bar{v}_e

How do you test a hypothesis using scientific inquiry
irina1246 [14]
Once you have constructed an effective hypothesis, the next step in the scientific inquiry process is to test the hypothesis through experimentation. This is a great opportunity for students to start a science notebook, if they have not yet started recording their progress. Steps to Identifying and Conducting an Appropriate Experiment to Test a Hypothesis 1) Present Hypotheses  Make a list of all potential hypotheses to be tested. 2) Make Predictions  For each hypothesis, ask what would be true if the hypothesis were true. 3) Write the Experimental Procedure  The experimental procedure is a step-by-step recipe for the science experiment. A good procedure contains enough detail that someone else could easily duplicate the experiment. Once you have formed a hypothesis, you will need to develop your experimental procedure to test whether your hypothesis is true or false. 4) Identify the Independent and Dependent Variables  The first step of designing the experimental procedure involves planning how to change the independent variable and how to measure the impact that this change has on the dependent variable. To guarantee a fair test when conducting the experiment, make sure that the only thing changing is the independent variable. All controlled variables must remain constant. 5) Design the Experiments  How can you identify an appropriate experiment that will effectively test your hypothesis? Begin by asking yourselves, “What can I do that will give me one result if my hypothesis is true, and a different result if my hypothesis is false?” Design at least one possible experiment for each hypothesis. Be sure that each experiment tests only one hypothesis.

How have organisms changed over time, according to the fossil record?​
Yuri [45]

Answer:

As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new conditions. This is the result of evolution of species over time.

hope this helps

have a good day :)

Which of the following reactions is spontaneous?
AveGali [126]
Answer is: <span>lumps os sugar dissolving in water.
Sugar has very good solubility in water and it dissolves readily, which is </span><span>example of a physical change.
</span>Gibbs free energy (G) determines if reaction will proceed spontaneously, if ΔG is negative, reaction is spontaneous <span>(ΔG = ΔH - T·ΔS).
</span>In other examples, reactions are spontaneous in reverse way, for example spontaneous is forming sodium chlorine from sodium metal and chlorine gas, but not sodium chloride forming sodium metal and chlorine gas, because a lot of energy is needed for that reaction.

Calculate the volume of the gas when the pressure of the gas is 1.60 atm at a temperature of 298 K. There are 160. mol of gas in
LekaFEV [45]

Answer:

2445 L

Explanation:

Given:  

Pressure = 1.60 atm

Temperature = 298 K

Volume = ?

n =  160 mol

Using ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 08206 L.atm/K.mol

Applying the equation as:

1.60 atm × V = 160 mol × 0.08206 L.atm/K.mol × 298 K  

<u>⇒V = 2445.39 L</u>

Answer to four significant digits, Volume = 2445 L
