What is high specific heat?

1 answer:

5 0

Specific heat capacity is the energy needed to raise the temrature of a substance of mass of 1kg by 1kelvin Q= Mc (delta) T delta T = change in temprature M = mass c= specific heat capacity q = energy if you take everything except C to be one Q will get bigger as C gets bigger

How do rock transformations on Venus and Earth indicate the planetary similarities between the two planets?

Gemiola [76]

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 10.0-milliliter sample of NaOH(aq) is neutralized by 40.0 milliliters of 0.50 M HCl. What is the molarity of the NaOH(aq)?

Ludmilka [50]

$\frac{10 mL}{1000 mL} = 0.01 L$

$\frac{40mL}{1000mL} =0.04L$

$M _{1} V_{1}=M_{2}V_{2}$

$M_{1}(0.01)=(0.50)(0.04)$

$M_{1}(0.01)=0.02$

$M_{1}= \frac{0.02}{0.01}$

$M_{1}=2$

A substance joined by this type of bond shares electrons

telo118 [61]

Answer: Covalent

Explanation:

A covalent compound is formed when an element shares its valence electron with another element. This compound is formed between two non metals. Example: $HF$

An ionic compound is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal. Example: $NaCl$

A sample of ammonia gas was allowed to come to equilibrium at 400 K. 2NH3(g) <---> N2(g) 3H2(g) At equilibrium, it was fou

Softa [21]

Answer:

Kc for this equilibrium is 2.30*10⁻⁶

Explanation:

Equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction and the concentrations of reactants and products are held constant.

Being:

aA + bB ⇔ cC + dD

the equilibrium constant Kc is defined as:

$Kc=\frac{[C]^{c}*[D]^{d} }{[A]^{a} *[B]^{b} }$

In other words, the constant Kc is equal to the multiplication of the concentrations of the products raised to their stoichiometric coefficients by the multiplication of the concentrations of the reactants also raised to their stoichiometric coefficients. Kc is constant for a given temperature, that is to say that as the reaction temperature varies, its value varies.

In this case, being:

2 NH₃(g) ⇔ N₂(g) + 3 H₂(g)

the equilibrium constant Kc is:

$Kc=\frac{[N_{2} ]*[H_{2} ]^{3} }{[NH_{3} ]^{2} }$

Being:

[N₂]= 0.0551 M
[H₂]= 0.0183 M
[NH₃]= 0.383 M

and replacing:

$Kc=\frac{0.0551*0.0183^{3} }{0.383^{2} }$

you get:

Kc= 2.30*10⁻⁶

<u><em>Kc for this equilibrium is 2.30*10⁻⁶</em></u>
