What is the balanced equation for the reaction of a solution of sodium sulfate is mixed with strontium chloride?

Answer:

5.9 × 10² kJ

Explanation:

When carbon disulfide, CS₂, forms from its elements, heat is absorbed. The corresponding value for the standard enthalpy of formation of carbon disulfide is 117.36 kJ/mol. The thermochemical equation that represents this process is:

C(graphite) + 2 S(s, rhombic) ⇒ CS₂(g)   ΔH°f = 117.36 kJ/mol

117.36 kJ of heat are absorbed when 1 mole of CS₂ is formed. The amount of heat absorbed when 5.0 moles of CS₂ are formed is:

5.0 mol × 117.36 kJ/mol = 5.9 × 10² kJ

Answer:

48 °C

Explanation:

q = 90J

m = 15 g

C = 0.126 J/gºC

q = mct

90 = (15)(0.126)t

t = 47.62 °C = 48 °C

Answer:

Explanation:

Formula

E = m * c * Δt

Δt is what you seek.

Givens

E = 90 joules

m = 15 grams

c   = 0.126

Solution

90 = 15 * 0.126 * Δt         Divide by 15

90/15 = 15/15 * 0.126 * Δt

6 = 0.126 * Δt                  Divide by 0.126

6/0.126 = Δt

47.619 = Δt

Δt = 48 oC

17 × ( 2 × 16 ) = 17 × 32 = 544 grams

Answer: The new temperature of container is 123 K.

Explanation:

Given: [tex]P_{1}[/tex] = 795 mm Hg,     [tex]T_{1}[/tex] = 273 K

[tex]P_{2}[/tex] = 358 mm Hg,          [tex]T_{2}[/tex] = ?

Formula used to calculate the new temperature is as follows.

[tex]\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}\\\frac{795 mm Hg}{273 K} = \frac{358 mm Hg}{T_{2}}\\T_{2} = 123 K[/tex]

Thus, we can conclude that the new temperature of container is 123 K.

Answer:

a: increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object

Explanation:

The oppositely charged objects attract each other more is option a. It increased the positive charge and the negative charge.

At the time when the  oppositely charged objects are attracted to each other more so here the positive charge should be increased with respect to the positive charge object and the negative charge is increased with respect to the negative charge object

Hence, the first option is correct.

Answer:

132.53 J/kg.°C

Explanation:

Applying,

Q = cm(t₂-t₁)................ Equation 1

Where Q = amount of heat, c = specific heat capacity of platinum metal, m = mass of platinum metal, t₁ = initial temperature, t₂ = Final temperature.

Make c the subeject of the equation

c = Q/m(t₂-t₁).............. Equation 2

From the question,

Given: Q = 5.7 J. m = 18.7 g = 0.0187 kg, t₁ = 21.2°C, t₂ = 23.5°C

Substitute these values into equation 2

c = 5.7/[0.0187×(23.5-21.2)]

c = 5.7/0.04301

c = 132.53 J/kg.°C

Venus

What is the Slowest Planet. Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe. If you walked along a bike path that circles its equator, you'd only need to go four miles an hour to keep night from ever falling on Venus.

Answer:

Venus

Explanation:

It rotates once every 243 days, by far the slowest rotation period of any of the major planets.

Answer:

The tectonic style and viability of modern plate tectonics in the early Earth is still debated. Field observations and theoretical arguments both in favor and against the uniformitarian view of plate tectonics back until the Archean continue to accumulate. Here, we present the first numerical modeling results that address for a hotter Earth the viability of subduction, one of the main requirements for plate tectonics. A hotter mantle has mainly two effects: 1) viscosity is lower, and 2) more melt is produced, which in a plate tectonic setting will lead to a thicker oceanic crust and harzburgite layer. Although compositional buoyancy resulting from these thick crust and harzburgite might be a serious limitation for subduction initiation, our modeling results show that eclogitization significantly relaxes this limitation for a developed, ongoing subduction process. Furthermore, the lower viscosity leads to more frequent slab breakoff, and sometimes to crustal separation from the mantle lithosphere. Unlike earlier propositions, not compositional buoyancy considerations, but this lithospheric weakness could be the principle limitation to the viability of plate tectonics in a hotter Earth. These results suggest a new explanation for the absence of ultrahigh-pressure metamorphism (UHPM) and blueschists in most of the Precambrian: early slabs were not too buoyant, but too weak to provide a mechanism for UHPM and exhumation.

Answer:

"500 Joule/sec" is the right answer.

Explanation:

The given values are:

Force,

F = 1000 N

Velocity,

s = 10 m

Time,

t = 20 s

Now,

The power will be:

=  [tex]\frac{Force\times Velocity}{Time}[/tex]

On putting the values, we get

=  [tex]\frac{1000\times 10}{20}[/tex]

=  [tex]\frac{10000}{20}[/tex]

=  [tex]500 \ Joule/sec[/tex]
