Answer:
H₃P phosphidic acid
Explanation:
The Trihydrogen monophosphide, as stated in the exercise, can act as an acid. This is pretty similar to the case of hydrogen chloride, which is a gas but it can also be an acid, in this case, chloridic acid.
In the case of trihydrogen phosphide, we can write it molecular formula which is:
H₃P
Now, this is a binary compound because its composed of only two elements, in this case, hydrogen and phosphide. To name binary acid, we need to name the non metal with the sufije idic, and then, the word acid.
Following this simple rule, the trihydrogen phosphide would be, as acid:
H₃P: phosphidic acid

What is a precipitation
reaction?
Answer:
A precipitation reaction is one in which substances in solution are mixed and an insoluble product is made. The insoluble product is called a precipitate and can be seen as a solid forming in the reaction mixture.
A 1.0 g sample of which substance contains the largest
number of molecules?
Answer:
Hydrogen (since this is all the info I'm working with)
Explanation:
Since we need to know how which substance has the most amount of molecules, we would need to look at the Atomic masses of these elements. Hydrogen has an atomic mass of 1.01g/mol whereas something like oxygen has an atomic mass of 16.00g/mol. Judging this, we can determine since a mole is made up of 6.02*10^23 molecules(Avogadro's number), and we have 1/1.01grams of hydrogen, we can deduce that Hydrogen would contain the largest amount of molecules
How do rock transformations on Venus and Earth indicate the planetary similarities between the two planets?
Answer:
Both the Earth and Venus show the appearance of igneous rocks due to the cooling of the magma.
Explanation:
As we know, ignea rock is the first step in the transformation of rocks. This rock is formed by the overflow of terrestrial magma which, upon cooling, turns into ignea rock, which will undergo metamorphism and transform into metamorphic rock, which will continue to undergo metamorphosis until it becomes the other rocks that complete the rock cycle. This is a terrestrial process that can be found on Venus, which also presents the cooling of magma in the formation of ignea rock, which will undergo metamorphism, transforming into other rocks, the way it occurs on Earth.

A farmer wants to build a pond for her cows. What step must she take in order to build the pond?
A. Dig into the zone of aeration.
B. Place a permeable material on the ground.
C. Keep the soil moist.
D. Place an impermeable material on the ground.
Answer:
Option A:
Dig into the zone of aeration
Explanation:
Within the lithosphere of the earth's surface, the zone of aeration is the zone directly above the water table, with a lot of pore spaces within the rocks. These pore spaces contain air and water, which can be used to water the cows.
Once the zone of aeration has been dug into, the farmer can tap into the underground reserve of water, which is stored within the pores of rocks. This water can now sip into the hole that was dug up by the farmer, forming a pond for the cows.
In order to expand agriculture and urban areas to meet increased demand for growing populations, water supplies often have to be diverted. In three to five sentences, construct a potential chain of consequences for what could happen when water is diverted from large bodies like lakes and rivers
Answer:
Decrease occur in the amount and flow of water bodies.
Explanation:
There is decrease in the amount and flow of water from water bodies such as rivers and lakes etc occur when the river is diverted from large water bodies because the water flows to the diverted sides and decrease occurs in the amount of water in the rivers and lakes. Those regions from where this river passes can also be negatively affected due to low amount of water they receives for their daily needs or for cultivation of crops so we can say that this diversion has adverse effect on other populations.

Which of the following could be the hypothesis supported by an investigation that demonstrates the law of conservation of mass in relation to chemical reactions?
A. If the reaction obeys the law of conservation of mass, then mass will be the same before and after the reaction.
B. If the reaction obeys the law of conservation of mass, then mass will increase after the reaction.
C. If the reaction obeys the law of conservation of mass, then mass will be different before and after the reaction.
D. If the reaction obeys the law of conservation of mass, then mass will decrease after the reaction.
According to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction. If the reaction obeys the law of conservation of mass, the mass before and after the reaction will be the same.
What does the law of conservation of mass?Any element's mass at the start of a reaction will equal its mass at the end of the reaction. Accounting for all reactants and products in a chemical reaction results in the same total mass at any point in time in any closed system.
When coal, for example, is burned, the carbon atom transforms into carbon dioxide. The carbon atom undergoes transformation from solid to gas, but its mass remains constant.
According to the law of conservation of mass, the amount of mass that enters a chemical reaction in the form of reactants must equal the amount of mass that exits the reaction process in the form of products. This is only possible in a closed system. For example, if 2g of reactant A reacts with 32g of reactant B, the mass of the product AB formed is 34g.

If 4.04g of h2 gas react with oxygen gas to create 36.36g of water, how many grams of oxygen reacted?
Answer:
gO₂ = 32.32 g
Explanation:
In this case, let's write the general equation:
2H₂ + O₂ -------> 2H₂O
In this case, we can use the 1° law, which is mass conservation. If the product has 36.36 g of water, then in the reactants we should have the same 36.36 g.
According to this, we already have 4.04 of hydrogen, then the remaining to reach the 36.36 g would be:
gO₂ = 36.36 - 4.04
gO₂ = 32.32 gHope this helps
Cuando se trata Ca3P2 con agua, los productos son Ca(OH)2 y PH3. Calcular el peso máximo obtenido al reaccionar 2 g de Ca3P2 con 1 g de H2O.
Answer:
0.629 gramos de PH3 es la máxima de cantidad que puede ser producida.
Explanation:
¡Hola!
En este caso, dado que tenemos la siguiente reacción química, la cual se puede balancear directamente:
[tex]Ca_3P_2+6H_2O\rightarrow 3Ca(OH)_2+2PH_3[/tex]
Podemos calcular la masa máxima de cualquier producto, digamos PH3, al comparar la masa de este, que 2 g the Ca3P2 y 1 g de H2O producen por separado y de acuerdo a la estequiometría:
[tex]2gCa_3P_2 *\frac{1molCa_3P_2 }{182.18gCa_3P_2 }*\frac{2molPH_3}{1molCa_3P_2 } *\frac{34gPH_3}{1molPH_3 } =0.747gPH_3\\\\1gH_2O *\frac{1molH_2O }{18.02gH_2O}*\frac{2molPH_3}{6molH_2O} *\frac{34gPH_3}{1molPH_3 } =0.629gPH_3[/tex]
De este modo, infermos que solamente 0.629 gramos the PH3 pueden ser obtenidos al ser el agua el reactivo límite.
¡Saludos!
