A network is the type of solid that has the weakest forces holding it together.
What is it meant by the network?A network, in computing, is a group of two or extra gadgets or nodes that could talk. The gadgets or nodes in question can be connected through physical or wi-fi connections. The key is that there are at least separate components, and they may be connected.
A home wireless LAN (wireless local area network, or Wi-Fi network) is a good example of a small client-server network. Various devices in the home are wirelessly connected to a router that acts as the central node (server) in the home.
A network is a collection of computers, servers, mainframes, community gadgets, peripherals, or other devices related to permitting facts sharing. An example of a network is the net, which connects hundreds of thousands of people everywhere in the global.

1. 24.76 grams of potassium carbonate (K2CO3) is reacted with an excess of aluminum nitrate (Al(NO3)3) to produce potassium nitrate (KNO3) and aluminum carbonate (Al2(CO3)3). How many grams of the product Al2(CO3)3 is formed? Round to the nearest hundredth.
Answers
Excess reagents are the chemical species that remain after the reaction completion. 14 gms of aluminum carbonate will be formed.
What are grams?Grams are the unit of the mass that is defined by the product of the moles and the molar mass of the substance.
The balanced chemical reaction is shown as:
3 K₂CO₃ + 2 Al(NO₃)₃ → Al₂(CO₃)₃ + 6 KNO₃
From the reaction, it can be said that 2 moles of aluminum nitrate are required to produce a mole of aluminum carbonate.
Moles of potassium carbonate are calculated as:
Moles = 24.76 gm ÷ 138.205 g/mol = 0.179 moles
If 3 moles of potassium carbonate produce 1 mole of aluminum carbonate, then 0.179 moles will produce 0.059 moles.
From the moles, mass is calculated as:
Mass = moles × molar mass
= 0.059 moles × 234.08 g/mol
= 13.97 gms
Therefore, 14 gms of aluminum carbonate will be formed.

How many grams of rubidium are in 2.39 x 10^24 atoms of rubidium?
Answers
Avogadro's number is the number of the particles in a mole of a substance. There are 339 grams of (Rb) rubidium in the sample.
What are atoms?Atoms are the fundamental of the matter that is unsplittable into fine particles.
We know, that 1 mole = 6.022 x 10²³ atoms
So, moles in 2.39 x 10²⁴ atoms will be calculated and converted into mass by using the molar mass of the substance.
2.39 x 10²⁴ × (1 ÷ 6.022 x 10²³) × 85.468 = 339 g Rb
Therefore, 339 g Rb is present in the sample.

Find the empirical formula of a compound containing 26.56% potassium, 34.51% chromium, and the remainder oxygen.
Answers
Answer:
K₂Cr₂O₇
Explanation:
Finding % of O
% O = 100% - % K - % Cr% O = 100% - 26.56% - 34.51%% O = 73.44% - 34.51%% O = 38.93%Steps
Change % of each element into grams.Convert grams of each element into moles by dividing grams by molar mass.Divide all moles by the smallest number of moles.If the moles are all whole numbers, then you’re done and that’s your empirical formula.If not, multiply all moles by number such that everything is a whole number.Solving
We have 26.56g of K, 34.51g of Cr, and 39.93g of O
Moles of K, n(K) = 26.56/39.0983 = 0.68 molesMoles of Cr, n(Cr) = 34.51/51.9961 = 0.66 molesMoles of O, n(O) = 38.93/15.9994 = 2.43 molesK = 0.68/0.66 ≈ 1 x 2 = 2Cr = 0.66/0.66 = 1 x 2 = 2O = 2.43/0.66 = 3.5 x 2 = 7The empirical formula is K₂Cr₂O₇
