Answer:
236.8 g
Explanation:
From the reaction equation;
CaC2 + 2H2O(I) --------> C2H2(g) + Ca(OH)2(aq)
Since;
1 mole of CaC2 yields 1 mole of Ca(OH)2
It follows that 3.20 moles of CaC2 also yields 3.2 moles of Ca(OH)2
Mass of Ca(OH)2 = number of moles * molar mass
molar mass of Ca(OH)2 = 74 g/mol
Mass of Ca(OH)2 = 3.20 moles * 74 g/mol =
Mass of Ca(OH)2 = 236.8 g
Answer: I think trans- prefix Definition of trans- (Entry 3 of 3) 1 : on or to the other side of : across : beyond transatlantic. 2a : beyond (a specified chemical element) in the periodic table transuranium
Explanation:
The prefix trans- and its variant tra-, which mean “across,” appear in many English vocabulary words, for example: transmit, transform, and trajectory. Consider the word translation, which is the carrying “across” from one language into another.

Ionic compounds are composed of a non-metal as the anion and a metal as the cation. Covalent compounds on the other hand are composed of both non-metals from both charges. In this case, OF2 is covalent, PBr3 is covalent, SeO2 is ionic, C5H12 is covalent, and CBr4 is covalent.
