Answer:
2.67 * 10-3 mol/L
Explanation:
Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. (Wikipedia)
Given that; C =kP
C= concentration of a dissolved gas = ?
k = Henry's Law constant = 9.71 x 10-4 mol/(L·atm)
P = partial pressure of the gas = 2.75 atm
So,
C = 9.71 x 10-4 mol/(L·atm) * 2.75 atm
C = 2.67 * 10-3 mol/L

Which is an example of a double
replacement reaction?
2Na+ Cl2 + 2NaCl
H2SO3 → H20 + S02
2K + 2H20 – 2KOH + H2
NaCl + AgF-NaF + AgCI
Answer:
NaCl + AgF → NaF + AgCl
Explanation:
A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products.
From all the reactions given ,
2Na + Cl₂ → 2NaCl is an example of combination reaction because two or more reactants (Na & Cl₂) react with each other to form a single product (NaCl)H₂SO₃ → H₂O + SO₂ is an example of decomposition reaction because a single reactant (H₂SO₃) breaks down into two or more products (H₂O & SO₂).2K + 2H₂O → 2KOH + H₂ is an example of displacement reaction because a highly reactive element (K) displaces a least reactive element (H) from its compound (H₂O).NaCl + AgF → NaF + AgCl is an example of double replacement reaction because there's an exchange between Cations ([tex]Na^+[/tex] & [tex]Ag^{+}[/tex]) and Anions ([tex]Cl^-[/tex] & [tex]F^-[/tex]).Emily and Jack are working on their chemistry homework together. Jack explains to Emily
that when element "B" reacts, it will gain one electron and become negative since
electrons are negative. Emily asks if this same element can become negative by taking
away a proton. If you were Jack, what would you explain to Emily?
the protons is theato.m if you take one away you change the element
Explanation:protons determine the element take away the proton and the element changes. That means that the same element cannot become negatively charged by taking away the protons

why do you think the pressure changed as it did when the temperature was increased?
Answer:
La Convención Marco de las Naciones Unidas sobre el Cambio Climático (CMNUCC) en su Artículo 1, lo define como ‘un cambio de clima atribuido directa o indirectamente a la actividad humana que altera la composición de la atmósfera mundial y que se suma a la variabilidad natural del clima observada durante períodos de tiempo comparables’. La CMNUCC distingue entre ‘cambio climático’ atribuido a actividades humanas que alteran la composición atmosférica y ‘variabilidad climática’ atribuida a causas naturales.
Los científicos han encontrado evidencias de que el clima en el planeta está cambiando a un ritmo más acelerado de lo esperado y que nuestras actividades ligadas a la producción, extracción, asentamiento y consumo, son la principal causa de este aceleramiento en el cambio.
El mayor problema de un cambio acelerado en el clima es que nuestras sociedades no están preparadas para asumir los cambios que esto nos pueda traer: derretimiento de las masas glaciares y nevados que abastecen acueductos, cambios en los ciclos de floración y fructificación de las plantas de cultivo, ascensos en el nivel de los mares donde hay mucha población viviendo, mayor ocurrencia y fuerza en lluvias, sequías, huracanes, heladas y granizadas en áreas urbanas y rurales, entre otros fenómenos que sin duda reducen nuestra calidad de vida.

A chemistry student experiments on producing table salt by reacting pure sodium cubes with confined chlorine gas. If the procedure is successful, how much salt is produced with 160 g of chlorine gas used? *
with solution pls
Answer: 263 grams of salt is produced.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Cl_2=\frac{160g}{71g/mol}=2.25moles[/tex]
The balanced chemical reaction is:
[tex]2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)[/tex]
According to stoichiometry :
1 mole of [tex]Cl_2[/tex] produce = 2 moles of [tex]NaCl[/tex]
Thus 2.25 moles of [tex]Cl_2[/tex] will produce =[tex]\frac{2}{1}\times 2.25=4.50moles[/tex] of [tex]NaCl[/tex]
Mass of [tex]NaCl=moles\times {\text {Molar mass}}=4.50moles\times 58.5g/mol=263g[/tex]
Thus 263 grams of salt is produced.
In a closed circuit the electricity cannot flow, the motor will not run.

Calculate the temperature when a 2.51L sample of gas at 25.0 °C is reduced to 1.75 L? (answer must be in K)
\Large \frac{V1}{T1}=\frac{V2}{T2}
Answer:
208 K
Explanation:
youre welcome
According to the Charle's law, when pressure is constant the temperature when a 2.51 L sample of gas at 25.0 °C is reduced to 1.75 L is 207.76 K.
What is pressure?Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.
There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .
It is a scalar quantity which is related to the vector area element with a normal force acting on it.It is distributed over solid boundaries and across arbitary sections of fluid normal to the boundaries at every point.As per Charle's law substitution of values gives T₂=298×1.75/2.51=207.76 K.
